Thanks for the replies. I managed it finally with ProxyPass and ProxyPassReverse What has caused all the headache was the fact that the backend server (application server that ran the forum) had a html meta refresh tag in it's /index.html and that did not get translated by the proxypass directives. I don't know whether this is normal behaviour or a bug. The request always came back with the refresh address of the backend server which could not be resolved or accessd by the client. -- Chris Christoph P. U. Kukulies kuku_at_kukulies.org response back to the client. That's not the way I understand the reverse proxy... the request *is handled by the backend server, the front end server is used to route the request. Some folks use mod_rewrite with mod_proxy to integrate the namespace so the backend server appears transparent, but what is really happening is that the URL's are rewritten on the fly.
