What does the error log on the IBM HTTP Server say ? What is the access log entry for that particular request on the IBM HTTP Server ? Is the request passed by the IBM HTTP Server to the WebSphere application server ?? Please verify the logs of the application server also. I assume you are using the WebSphere plugin ? I have not used that plugin for several years, but I seem to remember that it had its own log. What does that log say ? I suspect that you have may problem with the WebSphere plugin configuration. Your reverse proxy is listening on one HTTP port, and the IBM HTTP server on another. I suspect that the IBM HTTP Server does not intercept the request because the host:port it does not match what is defined in the plugin's configuration. The plugin is a bear to configure until you get a grip. The configuration file contains XML - you need to understand the structure of the XML, and the dependencies between XML elements. I think what you need to do is add a new VirtualHostGroup next to the existing one: <VirtualHostGroup Name="reverse_proxy"> <VirtualHost Name="*:80" /> <VirtualHost Name="*:443" /> </VirtualHostGroup> (if that does not work, try to add also <VirtualHost Name="*" />) Then you need to add a new route that associates the relevant server cluster and URI group with this new virtual host group, for example: <Route ServerCluster="server1_Cluster" UriGroup="server1_Cluster_URIs" VirtualHostGroup="reverse-proxy" /> Should everything else fail, please contact your friendly IBM representative. -ascs -----Original Message----- From: Ravish Agarwal [mailto:Ravish_Agarwal@xxxxxxxxxxx] Sent: Monday, July 10, 2006 11:20 AM To: Axel-Stéphane SMORGRAV Cc: users@xxxxxxxxxxxxxxxx Subject: RE: [users@httpd] Re: problem with mod_rewrite rewiterule with [P](internal proxying) Yes You are right in that. Requests are indeed proxied to the other IBM HTTP server. I get the same from the access logs of the same. However I am getting the HTTP 404 in the logs of that webserver. But theis is not the case when I directly communicate with it or without using the [P} option it works fine. What could be the problem? Can I increase the log level to solve the problem? -----Original Message----- From: Axel-Stéphane SMORGRAV [mailto:Axel-Stephane.SMORGRAV@xxxxxxxxxxxxxx] Sent: Monday, July 10, 2006 11:53 AM To: Ravish Agarwal Subject: RE: [users@httpd] Re: problem with mod_rewrite rewiterule with [P](internal proxying) The entry in the rewrite log that says "go-ahead with proxy request", indicates that the request is indeed proxied through to mgtpdma3.rau.valmet.com:7003. Now what you need to do is check the logs on mgtpdma3.rau.valmet.com:7003 to see if the request actually came through. If it did, what was the URL requested, and do the error logs say anything that would give a clue about why it returned a 404 ? -ascs --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
