Sticky sessions isn't working through Apache httpd load balancer when passing the root context to another

Issue

• Sticky sessions are not being properly maintained when we're routing requests from the root context on httpd to the application context on our JBoss backend, for example:

      ProxyPass / balancer://mycluster/appContext/ stickysession=JSESSIONID
  

• The session cookie is not being properly pass along with subsequent requests, and JBoss is creating a new cookie with each request.

• When an empty path cookie is present and used in the request with mod_cluster, it fails after immediate errors saying that all workers are in error state.

• What does the SessionCookie path does?
