Issue

Trying to access a http url that is secured using Windows Challenge/Response (NTLM) authentication fails with the camel-http component and returns a 401 HTTP response code.

The Camel route calls the http url similar to this example

from("timer:MyTimer?repeatCount=1")
.to("http://192.168.178.24:80/iisstart.htm?authMethod=NTLM&authMethodPriority=NTLM&authUsername=tmielke&authPassword=XXX&authDomain=myDomain&authHost=192.168.178.24")
.convertBodyTo(java.lang.String.class)
.to("log:MyLogger?showAll=true");
