Hey, thanks for your help. I tried ping, nslookup which both work. I even tried lynx and was able to bring up the page directly. I set LogLevel to "debug" and had a look in my error.log: [Mon Jan 16 23:28:23 2006] [notice] Apache/1.3.29 (Unix) mod_ssl/2.8.16 OpenSSL/ 0.9.7g configured -- resuming normal operations [Mon Jan 16 23:28:23 2006] [info] Server built: unknown [Mon Jan 16 23:28:23 2006] [notice] Accept mutex: sysvsem (Default: sysvsem) [Mon Jan 16 23:28:26 2006] [debug] proxy_cache.c(0): Request for http://internal.foo.org/favicon.ico, pragma_req=(unset), ims=0 [Mon Jan 16 23:28:26 2006] [debug] proxy_util.c(0): File /var/cache/Q/S/j/EGecnq Rx1ZGkeYQFKdg not found [Mon Jan 16 23:28:26 2006] [debug] proxy_cache.c(0): Local copy not present or e xpired.

Declining. ------------------------------- Is all I get. I got the idea that maybe it was the caching that was the problem so I took out all caching directives then restarted apache and got a log like this: [Mon Jan 16 23:29:36 2006] [notice] Apache/1.3.29 (Unix) mod_ssl/2.8.16 OpenSSL/ 0.9.7g configured -- resuming normal operations [Mon Jan 16 23:29:36 2006] [info] Server built: unknown [Mon Jan 16 23:29:36 2006] [notice] Accept mutex: sysvsem (Default: sysvsem) [Mon Jan 16 23:29:43 2006] [debug] proxy_cache.c(0): No CacheRoot, so no caching . Declining. ------------------------------- With the same result... FYI when I set ProxyPass to an IP (which works) my error log shows: [Mon Jan 16 23:36:31 2006] [debug] proxy_cache.c(0): Request for http://172.16.0.5/, pragma_req=(unset), ims=0 [Mon Jan 16 23:36:31 2006] [debug] proxy_util.c(0): File /var/cache/4/g/H/NhiNLMZwLXwWY9wfp2w not found [Mon Jan 16 23:36:31 2006] [debug] proxy_cache.c(0): Local copy not present or expired.

It's horrible to post logs =/ -pat Quoting Axel-Stéphane SMORGRAV <Axel-Stephane.SMORGRAV@xxxxxxxxxxxxxx>:
What was I thinking - since it worked with the IP address. It does say "Host not found". Make sure that your host is able to resolve the FQDN of the backend server (nslookup intranet.foo.org, or ping intranet.foo.org). Also check the (error) logs to see exactly what URL produced the 500 error to make sure that it is not the consequence of a redirect. -ascs -----Original Message----- From: bsdsec@xxxxxxxxxxxxxxxxxxxxxx [mailto:bsdsec@xxxxxxxxxxxxxxxxxxxxxx] Sent: Monday, January 16, 2006 1:48 PM To: Axel-Stéphane SMORGRAV Subject: RE: [users@httpd] ProxyPass does not work with hostnames onlyIP's. (mod_proxyApache 1.3) Sorry I forgot to mention, OpenBSD comes with Apache 1.3 by default. I'm using APche 1.3 Quoting Axel-Stéphane SMORGRAV <Axel-Stephane.SMORGRAV@xxxxxxxxxxxxxx>:I will assume that you are using Apache 2.0 or newer. In that case, in addition to mod_proxy, you need to include the mod_proxy_http module. -ascs -----Original Message----- From: bsdsec@xxxxxxxxxxxxxxxxxxxxxx [mailto:bsdsec@xxxxxxxxxxxxxxxxxxxxxx] Sent: Monday, January 16, 2006 1:41 PM To: users@xxxxxxxxxxxxxxxx Subject: [users@httpd] ProxyPass does not work with hostnames only IP's. (mod_proxyApache 1.3) Hi! I'm using OpenBSD 3.8 default install with mod_proxy enabled. I use ProxyPass in virtual host directives with success. Example: <VirtualHost 10.5.5.20> ServerName www.foo.org ProxyPass / http://172.16.0.5/ ProxyPassReverse / http://172.16.0.5/ <Location /> Order deny,allow Allow from all </Location> </VirtualHost> ...which works fine! The problem occurs when I want to use a hostname instead of an IP, e.g.: ProxyPass / http://intranet.foo.org/ ProxyPassReverse / http://intranet.foo.org/ All I get is a "500 Proxy Error" page: ------------------------------------------------- Proxy Error The proxy server could not handle the request GET /. Reason: Host not found ------------------------------------------------- Every page I've read seems to indicate you can use hostnames in ProxyPass directive. The proxy can resolve "intranet.foo.org" and access the webpage at that address just fine. It simply wont proxy to it! Any help would be appreciated. Thanks, Patrick Halimee
