```
    Description copied from interface: HttpServletRequest
    
    Returns all the values of the specified request header as an Enumeration of String objects.
    Some headers, such as Accept-Language can be sent by clients as several headers each with a different value rather than sending the header as a comma separated list.
    If the request did not include any headers of the specified name, this method returns an empty Enumeration. The header name is case insensitive. You can use this method with any request header.
    
    Specified by:

```
    Description copied from interface: HttpServletRequest
    
    Returns an enumeration of all the header names this request contains. If the request has no headers, this method returns an empty enumeration.
    Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null
    
    Specified by:
    
    getHeaderNames in interface HttpServletRequest
    
    Returns:
    
    an enumeration of all the header names sent with this request; if the request has no headers, an empty enumeration; if the servlet container does not allow servlets to use this method, null
  - getHttpServletMapping
```
public HttpServletMapping getHttpServletMapping()
```
    Description copied from interface: HttpServletRequest
    
    Return the HttpServletMapping by which the HttpServlet for this HttpServletRequest was invoked. The mappings for any applicable Filters are not indicated in the result. If the currently active Servlet invocation was obtained by a call to ServletRequest.getRequestDispatcher(java.lang.String) followed by a call to RequestDispatcher.forward(javax.servlet.ServletRequest, javax.servlet.ServletResponse), the returned HttpServletMapping is the one corresponding to the path used to obtain the RequestDispatcher. If the currently active Servlet invocation was obtained by a call to ServletRequest.getRequestDispatcher(java.lang.String) followed by a call to RequestDispatcher.include(javax.servlet.ServletRequest, javax.servlet.ServletResponse), the returned HttpServletMapping is the one corresponding to the path that caused the first Servlet in the invocation sequence to be invoked. If the currently active Servlet invocation was obtained by a call to AsyncContext.dispatch(), the returned HttpServletMapping is the one corresponding to the path that caused the first Servlet in the invocation sequence to be invoked. See RequestDispatcher.FORWARD_MAPPING, RequestDispatcher.INCLUDE_MAPPING and AsyncContext.ASYNC_MAPPING for additional request attributes related to HttpServletMapping. If the currently active Servlet invocation was obtained by a call to ServletContext.getNamedDispatcher(java.lang.String), the returned HttpServletMapping is the one corresponding to the path for the mapping last applied to this request.
    
    The returned object is immutable. Servlet 4.0 compliant implementations must override this method.
    
    Specified by:
    
    getHttpServletMapping in interface HttpServletRequest
    
    Returns:
    
    An instance of HttpServletMapping describing the manner in which the current request was invoked.
  - getIntHeader
```
public int getIntHeader(String name)
```
    Description copied from interface: HttpServletRequest
    
    Returns the value of the specified request header as an int. If the request does not have a header of the specified name, this method returns -1. If the header cannot be converted to an integer, this method throws a NumberFormatException.
    The header name is case insensitive.
    
    Specified by:
    
    getIntHeader in interface HttpServletRequest
    
    Parameters:
    
    name - a String specifying the name of a request header

    an integer expressing the value of the request header or -1 if the request doesn't have a header of this name
  - getMethod
```
public String getMethod()
```
    Description copied from interface: HttpServletRequest
    
    Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT. Same as the value of the CGI variable REQUEST_METHOD.
    
    Specified by:
    
    getMethod in interface HttpServletRequest
    
    Returns:
    
    a String specifying the name of the method with which this request was made
  - getPathInfo
```
public String getPathInfo()
```
    Description copied from interface: HttpServletRequest
    
    Returns any extra path information associated with the URL the client sent when it made this request. The extra path information follows the servlet path but precedes the query string and will start with a "/" character.
    This method returns null if there was no extra path information.
    Same as the value of the CGI variable PATH_INFO.
    
    Specified by:
    
    getPathInfo in interface HttpServletRequest
    
    Returns:
    
    a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information
  - getPathTranslated
```
public String getPathTranslated()
```
    Description copied from interface: HttpServletRequest
    
    Returns any extra path information after the servlet name but before the query string, and translates it to a real path. Same as the value of the CGI variable PATH_TRANSLATED.
    If the URL does not have any extra path information, this method returns null or the servlet container cannot translate the virtual path to a real path for any reason (such as when the web application is executed from an archive). The web container does not decode this string.
    
    Specified by:
    
    getPathTranslated in interface HttpServletRequest
    
    Returns:
    
    a String specifying the real path, or null if the URL does not have any extra path information
  - getContextPath
```
public String getContextPath()
```
    Description copied from interface: HttpServletRequest
    
    Returns the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. For servlets in the default (root) context, this method returns "". The container does not decode this string.
    It is possible that a servlet container may match a context by more than one context path. In such cases this method will return the actual context path used by the request and it may differ from the path returned by the ServletContext.getContextPath() method. The context path returned by ServletContext.getContextPath() should be considered as the prime or preferred context path of the application.
    
    Specified by:
    
    getContextPath in interface HttpServletRequest
    
    Returns:
    
    a String specifying the portion of the request URI that indicates the context of the request
    
    See Also:
    
    ServletContext.getContextPath()
  - getQueryString
```
public String getQueryString()
```
    Description copied from interface: HttpServletRequest
    
    Returns the query string that is contained in the request URL after the path. This method returns null if the URL does not have a query string. Same as the value of the CGI variable QUERY_STRING.
    
    Specified by:
    
    getQueryString in interface HttpServletRequest
    
    Returns:
    
    a String containing the query string or null if the URL contains no query string. The value is not decoded by the container.
  - getRemoteUser
```
public String getRemoteUser()
```
    Description copied from interface: HttpServletRequest
    
    Returns the login of the user making this request, if the user has been authenticated, or null if the user has not been authenticated. Whether the user name is sent with each subsequent request depends on the browser and type of authentication. Same as the value of the CGI variable REMOTE_USER.
    
    Specified by:
    
    getRemoteUser in interface HttpServletRequest
    
    Returns:
    
    a String specifying the login of the user making this request, or null if the user login is not known

```
public boolean isUserInRole(String role)
```
    Description copied from interface: HttpServletRequest
    
    Returns a boolean indicating whether the authenticated user is included in the specified logical "role". Roles and role membership can be defined using deployment descriptors. If the user has not been authenticated, the method returns false.
    The role name "*" should never be used as an argument in calling isUserInRole. Any call to isUserInRole with "*" must return false. If the role-name of the security-role to be tested is "**", and the application has NOT declared an application security-role with role-name "**", isUserInRole must only return true if the user has been authenticated; that is, only when HttpServletRequest.getRemoteUser() and HttpServletRequest.getUserPrincipal() would both return a non-null value. Otherwise, the container must check the user for membership in the application role.
    
    Specified by:
    
    isUserInRole in interface HttpServletRequest
    
    Parameters:
    
    role - a String specifying the name of the role
    
    Returns:
    
    a boolean indicating whether the user making this request belongs to a given role; false if the user has not been authenticated
  - getUserPrincipal
```
public Principal getUserPrincipal()
```
    Description copied from interface: HttpServletRequest
    
    Returns a java.security.Principal object containing the name of the current authenticated user. If the user has not been authenticated, the method returns null.
    
    Specified by:
    
    getUserPrincipal in interface HttpServletRequest
    
    Returns:
    
    a java.security.Principal containing the name of the user making this request; null if the user has not been authenticated
  - getRequestedSessionId
```
public String getRequestedSessionId()
```
    Description copied from interface: HttpServletRequest
    
    Returns the session ID specified by the client. This may not be the same as the ID of the current valid session for this request. If the client did not specify a session ID, this method returns null.
    
    Specified by:
    
    getRequestedSessionId in interface HttpServletRequest
    
    Returns:
    
    a String specifying the session ID, or null if the request did not specify a session ID
    
    See Also:

    Specified by:
    
    changeSessionId in interface HttpServletRequest
    
    Returns:
    
    the new session id
  - getRequestURI
```
public String getRequestURI()
```
    Description copied from interface: HttpServletRequest
    
    Returns the part of this request's URL from the protocol name up to the query string in the first line of the HTTP request. The web container does not decode this String. For example:
    
    First line of HTTP request Returned Value
    POST /some/path.html HTTP/1.1 /some/path.html
    GET http://foo.bar/a.html HTTP/1.0 /a.html
    HEAD /xyz?a=b HTTP/1.1 /xyz
    
    To reconstruct an URL with a scheme and host, use HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest).
    
    Specified by:
    
    getRequestURI in interface HttpServletRequest
    
    Returns:
    
    a String containing the part of the URL from the protocol name up to the query string
    
    See Also:
    
    HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest)
  - getRequestURL
```
public StringBuffer getRequestURL()
```
    Description copied from interface: HttpServletRequest
    
    Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.
    If this request has been forwarded using RequestDispatcher.forward(javax.servlet.ServletRequest, javax.servlet.ServletResponse), the server path in the reconstructed URL must reflect the path used to obtain the RequestDispatcher, and not the server path specified by the client.
    Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append query parameters.
    This method is useful for creating redirect messages and for reporting errors.
    
    Specified by:
    
    getRequestURL in interface HttpServletRequest
    
    Returns:
    
    a StringBuffer object containing the reconstructed URL
  - getServletPath
```
public String getServletPath()
```
    Description copied from interface: HttpServletRequest
    
    Returns the part of this request's URL that calls the servlet. This path starts with a "/" character and includes either the servlet name or a path to the servlet, but does not include any extra path information or a query string. Same as the value of the CGI variable SCRIPT_NAME.
    This method will return an empty string ("") if the servlet used to process this request was matched using the "/*" pattern.
    
    Specified by:
    
    getServletPath in interface HttpServletRequest
    
    Returns:
    
    a String containing the name or path of the servlet being called, as specified in the request URL, decoded, or an empty string if the servlet used to process the request is matched using the "/*" pattern.
  - getSession
```
public HttpSession getSession(boolean create)
```
    Description copied from interface: HttpServletRequest
    
    Returns the current HttpSession associated with this request or, if there is no current session and create is true, returns a new session.
    If create is false and the request has no valid HttpSession, this method returns null.
    To make sure the session is properly maintained, you must call this method before the response is committed. If the container is using cookies to maintain session integrity and is asked to create a new session when the response is committed, an IllegalStateException is thrown.
    
    Specified by:
    
    getSession in interface HttpServletRequest
    
    Parameters:
    
    create - true to create a new session for this request if necessary; false to return null if there's no current session

  - getAttribute
```
public Object getAttribute(String name)
```
    Description copied from interface: ServletRequest
    
    Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.
    Attributes can be set two ways. The servlet container may set attributes to make available custom information about a request. For example, for requests made using HTTPS, the attribute javax.servlet.request.X509Certificate can be used to retrieve information on the certificate of the client. Attributes can also be set programatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.
    Attribute names should follow the same conventions as package names. This specification reserves names matching java.*, javax.*, and sun.*.
    
    Specified by:
    
    getAttribute in interface ServletRequest
    
    Parameters:

  - getCharacterEncoding
```
public String getCharacterEncoding()
```
    Description copied from interface: ServletRequest
    
    Returns the name of the character encoding used in the body of this request. This method returns null if no request encoding character encoding has been specified. The following methods for specifying the request character encoding are consulted, in decreasing order of priority: per request, per web app (using ServletContext.setRequestCharacterEncoding(java.lang.String), deployment descriptor), and per container (for all web applications deployed in that container, using vendor specific configuration).
    
    Specified by:

    If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.
    If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.
    
    Specified by:

```
    Description copied from interface: ServletRequest
    
    Stores an attribute in this request. Attributes are reset between requests. This method is most often used in conjunction with RequestDispatcher.
    Attribute names should follow the same conventions as package names. Names beginning with java.*, javax.*, and com.sun.*, are reserved for use by Sun Microsystems.
    If the object passed in is null, the effect is the same as calling ServletRequest.removeAttribute(java.lang.String).
    It is warned that when the request is dispatched from the servlet resides in a different web application by RequestDispatcher, the object set by this method may not be correctly retrieved in the caller servlet.

    Specified by:
    
    getLocale in interface ServletRequest
    
    Returns:
    
    the preferred Locale for the client
  - getLocales
```
public Enumeration<Locale> getLocales()
```
    Description copied from interface: ServletRequest
    
    Returns an Enumeration of Locale objects indicating, in decreasing order starting with the preferred locale, the locales that are acceptable to the client based on the Accept-Language header.

```
public RequestDispatcher getRequestDispatcher(String path)
```
    Description copied from interface: ServletRequest
    
    Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.
    The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.
    The difference between this method and ServletContext.getRequestDispatcher(java.lang.String) is that this method can take a relative path.
    
    Specified by:
    
    getRequestDispatcher in interface ServletRequest

  - startAsync
```
public AsyncContext startAsync()
                        throws IllegalStateException
```
    Description copied from interface: ServletRequest
    
    Puts this request into asynchronous mode, and initializes its AsyncContext with the original (unwrapped) ServletRequest and ServletResponse objects.
    Calling this method will cause committal of the associated response to be delayed until AsyncContext.complete() is called on the returned AsyncContext, or the asynchronous operation has timed out.
    Calling AsyncContext.hasOriginalRequestAndResponse() on the returned AsyncContext will return true. Any filters invoked in the outbound direction after this request was put into asynchronous mode may use this as an indication that any request and/or response wrappers that they added during their inbound invocation need not stay around for the duration of the asynchronous operation, and therefore any of their associated resources may be released.
    This method clears the list of AsyncListener instances (if any) that were registered with the AsyncContext returned by the previous call to one of the startAsync methods, after calling each AsyncListener at its onStartAsync method.
    Subsequent invocations of this method, or its overloaded variant, will return the same AsyncContext instance, reinitialized as appropriate.
    
    Specified by:
    
    startAsync in interface ServletRequest
    
    Returns:
    
    the (re)initialized AsyncContext
    
    Throws:
    
    IllegalStateException - if this request is within the scope of a filter or servlet that does not support asynchronous operations (that is, ServletRequest.isAsyncSupported() returns false), or if this method is called again without any asynchronous dispatch (resulting from one of the AsyncContext.dispatch() methods), is called outside the scope of any such dispatch, or is called again within the scope of the same dispatch, or if the response has already been closed

public AsyncContext startAsync(ServletRequest servletRequest,
                               ServletResponse servletResponse)
                        throws IllegalStateException
```
    Description copied from interface: ServletRequest
    
    Puts this request into asynchronous mode, and initializes its AsyncContext with the given request and response objects.
    The ServletRequest and ServletResponse arguments must be the same instances, or instances of ServletRequestWrapper and ServletResponseWrapper that wrap them, that were passed to the service method of the Servlet or the doFilter method of the Filter, respectively, in whose scope this method is being called.
    Calling this method will cause committal of the associated response to be delayed until AsyncContext.complete() is called on the returned AsyncContext, or the asynchronous operation has timed out.
    Calling AsyncContext.hasOriginalRequestAndResponse() on the returned AsyncContext will return false, unless the passed in ServletRequest and ServletResponse arguments are the original ones or do not carry any application-provided wrappers. Any filters invoked in the outbound direction after this request was put into asynchronous mode may use this as an indication that some of the request and/or response wrappers that they added during their inbound invocation may need to stay in place for the duration of the asynchronous operation, and their associated resources may not be released. A ServletRequestWrapper applied during the inbound invocation of a filter may be released by the outbound invocation of the filter only if the given servletRequest, which is used to initialize the AsyncContext and will be returned by a call to AsyncContext.getRequest(), does not contain said ServletRequestWrapper. The same holds true for ServletResponseWrapper instances.
    This method clears the list of AsyncListener instances (if any) that were registered with the AsyncContext returned by the previous call to one of the startAsync methods, after calling each AsyncListener at its onStartAsync method.
    Subsequent invocations of this method, or its zero-argument variant, will return the same AsyncContext instance, reinitialized as appropriate. If a call to this method is followed by a call to its zero-argument variant, the specified (and possibly wrapped) request and response objects will remain locked in on the returned AsyncContext.
    
    Specified by:
    
    startAsync in interface ServletRequest
    
    Parameters:
    
    servletRequest - the ServletRequest used to initialize the AsyncContext
    
    servletResponse - the ServletResponse used to initialize the AsyncContext
    
    Returns:
    
    the (re)initialized AsyncContext
    
    Throws:
    
    IllegalStateException - if this request is within the scope of a filter or servlet that does not support asynchronous operations (that is, ServletRequest.isAsyncSupported() returns false), or if this method is called again without any asynchronous dispatch (resulting from one of the AsyncContext.dispatch() methods), is called outside the scope of any such dispatch, or is called again within the scope of the same dispatch, or if the response has already been closed
  - isAsyncStarted
```
public boolean isAsyncStarted()
```
    Description copied from interface: ServletRequest
    
    Checks if this request has been put into asynchronous mode.
    A ServletRequest is put into asynchronous mode by calling ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest,ServletResponse) on it.
    This method returns false if this request was put into asynchronous mode, but has since been dispatched using one of the AsyncContext.dispatch() methods or released from asynchronous mode via a call to AsyncContext.complete().
    
    Specified by:
    
    isAsyncStarted in interface ServletRequest
    
    Returns:
    
    true if this request has been put into asynchronous mode, false otherwise
  - isAsyncSupported
```
public boolean isAsyncSupported()
```
    Description copied from interface: ServletRequest
    
    Checks if this request supports asynchronous operation.
    Asynchronous operation is disabled for this request if this request is within the scope of a filter or servlet that has not been annotated or flagged in the deployment descriptor as being able to support asynchronous handling.
    
    Specified by:
    
    isAsyncSupported in interface ServletRequest
    
    Returns:
    
    true if this request supports asynchronous operation, false otherwise
  - getAsyncContext
```
public AsyncContextImpl getAsyncContext()
```
    Description copied from interface: ServletRequest
    
    Gets the AsyncContext that was created or reinitialized by the most recent invocation of ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest,ServletResponse) on this request.
    
    Specified by:
    
    getAsyncContext in interface ServletRequest
    
    Returns:
    
    the AsyncContext that was created or reinitialized by the most recent invocation of ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest,ServletResponse) on this request
  - getAsyncContextInternal
```
public AsyncContextImpl getAsyncContextInternal()
```
  - getDispatcherType
```
public DispatcherType getDispatcherType()
```
    Description copied from interface: ServletRequest
    
    Gets the dispatcher type of this request.
    The dispatcher type of a request is used by the container to select the filters that need to be applied to the request: Only filters with matching dispatcher type and url patterns will be applied.
    Allowing a filter that has been configured for multiple dispatcher types to query a request for its dispatcher type allows the filter to process the request differently depending on its dispatcher type.
    The initial dispatcher type of a request is defined as DispatcherType.REQUEST. The dispatcher type of a request dispatched via RequestDispatcher.forward(ServletRequest, ServletResponse) or RequestDispatcher.include(ServletRequest, ServletResponse) is given as DispatcherType.FORWARD or DispatcherType.INCLUDE, respectively, while the dispatcher type of an asynchronous request dispatched via one of the AsyncContext.dispatch() methods is given as DispatcherType.ASYNC. Finally, the dispatcher type of a request dispatched to an error page by the container's error handling mechanism is given as DispatcherType.ERROR.
    
    Specified by:
    
    getDispatcherType in interface ServletRequest
    
    Returns:
    
    the dispatcher type of this request

```
public PushBuilder newPushBuilder()
```
    Description copied from interface: HttpServletRequest
    
    Instantiates a new instance of PushBuilder for issuing server push responses from the current request. This method returns null if the current connection does not support server push, or server push has been disabled by the client via a SETTINGS_ENABLE_PUSH settings frame value of 0 (zero).
    
    Specified by:
    
    newPushBuilder in interface HttpServletRequest
    
    Returns:
    
    a PushBuilder for issuing server push responses from the current request, or null if push is not supported
  - getTrailerFields
```
public Map<String,String> getTrailerFields()
```
    Description copied from interface: HttpServletRequest
    
    Get the request trailer fields.
    The returned map is not backed by the HttpServletRequest object, so changes in the returned map are not reflected in the HttpServletRequest object, and vice-versa.
    
    HttpServletRequest.isTrailerFieldsReady() should be called first to determine if it is safe to call this method without causing an exception.
    
    Specified by:
    
    getTrailerFields in interface HttpServletRequest
    
    Returns:
    
    A map of trailer fields in which all the keys are in lowercase, regardless of the case they had at the protocol level. If there are no trailer fields, yet HttpServletRequest.isTrailerFieldsReady() is returning true, the empty map is returned.
  - isTrailerFieldsReady
```
public boolean isTrailerFieldsReady()
```
    Description copied from interface: HttpServletRequest
    Return a boolean indicating whether trailer fields are ready to read using HttpServletRequest.getTrailerFields(). This methods returns true immediately if it is known that there is no trailer in the request, for instance, the underlying protocol (such as HTTP 1.0) does not supports the trailer fields, or the request is not in chunked encoding in HTTP 1.1. And the method also returns true if both of the following conditions are satisfied:
    1. the application has read all the request data and an EOF indication has been returned from the ServletRequest.getReader() or ServletRequest.getInputStream().
    2. all the trailer fields sent by the client have been received. Note that it is possible that the client has sent no trailer fields.
    Specified by:
    
    isTrailerFieldsReady in interface HttpServletRequest
    
    Returns:
    
    a boolean whether trailer fields are ready to read
