mod_cluster does not maintain sticky sessions when proxying one context on httpd to another on JBoss

Issue

• When we configure mod_cluster to proxy pass one root context on httpd to another on JBoss, sticky sessions are not maintained. Our config is something like:

    ProxyPass        /foo balancer://mycluster/bar   stickysession=JSESSIONID|jsessionid nofailover=On
    ProxyPassReverse /foo balancer://mycluster/bar
    ProxyPassReverseCookiePath  /bar   /foo
