Hi,

I am struggling with getting an Apache server as Reverse Proxy for a RAP-2.2 application. I realize this is probably a question for an Apache forum, but I have the feeling the problem is specific to the nature of RAP applications.

Everything is working fine EXCEPT that the first time the browser hits the site, I ALWAYS get this jetty error in the browser:

HTTP ERROR: 404

Problem accessing /mycontextmycontext;jsessionid=8mwr5mq62b8r1a4gt5c2skm2o. Reason:

ProxyServlet: /mycontextmycontext;jsessionid=8mwr5mq62b8r1a4gt5c2skm2o

If I open the link a second time, all is well.

In my Apache virtual host entry I have:

ProxyPass /rwt-resources http://192.169.1.10:12345/rwt-resources
ProxyPass /mycontext http://192.168.0.10:12345/mycontext
ProxyPass / http://192.168.0.10:12345/mycontext

ProxyPassReverse / http://192.168.0.10:12345/mycontext

Any suggestion is highly appreciated.

Not quite sure if this is the preferred solution, but the settings below seem to work, as long as the context is passed into the URL: http://theserver.com/mycontext

# We need the balancer the pass the sessionId on to Jetty.
ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid nofailover=On
ProxyPass /rwt-resources balancer://mycluster/ stickysession=JSESSIONID|jsessionid nofailover=On
<Proxy balancer://mycluster>
    BalancerMember http://192.168.1.10:12345
</Proxy>

Cheers,

E.

With the configuration below it is possible to access the site w/o specifying the context (http://myhost.com) instead of http://myhost.com/mycontext

    # The order of the lines below is important.
    ProxyPass   /rwt-resources http://192.168.1.10:12345/rwt-resources
    # We need the ProxyPassMatch here so we can pass:
    # /mycontext;jsessionid=180n7dktdjjld3tl11pd9ufof on to Jetty
    ProxyPassMatch   ^/(mycontext.*)$   http://192.168.1.10:12345/$1

    ProxyPassReverse /mycontext     http://192.168.1.10:12345/mycontext
    ProxyPassReverse /rwt-resources http://192.168.1.10:12345/rwt-resources

    ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid nofailover=On
    <Proxy balancer://mycluster>
        BalancerMember http://192.168.1.10:12345/mycontext/
    </Proxy>
