Re: Redirect after post Issue
I got it working. Basically the ProxyPassReverse directive should use HTTP not AJP.

Re: Redirect after post Issue
Looking at your mod_proxy config again I noticed that you are using ProxyPreserveHost on. I think this is causing the problems, you should remove this directive. What I think is happening is this: 1) Wicket says: redirect to /web/ 2) Tocmat makes the url absolute by prepending the virtual host. Since you have ProxyPreserveHost on, tomcat sees the virtual host as localhost and NOT localhost:8080, and returns http://localhost/web/xxx as the new lcoation. 3) Apache mod_proxy does NOT reverse proxy the url, because it does not have the :8080 on it and does not match your rule. If you remove the ProxyPreserveHost on, tomcat will return http://localhost:8080/web/x as the redirect location and Apache will reverse proxy it. The only downside of this is that your wicket app will not know the REAL virtual host, and so automatically generated absolute URL's (for example in emails) will be wrong.

Re: Redirect after post Issue
Slight correction: With IRequestCycleSettings.ONE_PASS_RENDER most form submits seem to work except in the case of continueToOriginalDestination... Everything else still fails.

Re: Redirect after post Issue
http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#proxypassreverse This directive lets Apache adjust the URL in the Location, Content-Location and URI headers on HTTP redirect responses ProxyPassReverse is the culprit here, not anything to do with Wicket.

Re: Redirect after post Issue
No problem, I know other people are doing this, I can't seem to see where the issue is... Which is why I think something is wrong either in Tomcat or Wicket.
