I've searched the archives here and elsewhere and see similar situations, but with slightly different symptoms, and the solutions aren't quite nailing my problem. SquirrelMail 1.4.17 (vanilla, no plugins) Apache 2.2.11 PHP 5.2.8 FreeBSD 7.0 Mail server is behind a firewall and outside traffic is via Apache reverse proxy setup (mod_proxy). Everything works great, with one exception: when choosing one or more messages from the squirrelmail list in the right-hand frame, and performing any action on them (delete, move, etc.), the action is completed, but the right frame is refreshed with "The requested URL /webmail/webmail/src/right_main.php was not found on this server". The corresponding Apache log reads, not surprisingly, "File does not exist: /usr/local/www/squirrelmail/ webmail" Obviously this is more a mod_proxy problem that a SM problem, except for the fact that (1) all other proxied web apps configured the same way work for us; and (2) it's a little odd to me that everything else works (e.g. deleting a single message), but I haven't dug into the SM code yet. Here is my mod_proxy configuration in httpd.conf: ProxyRequests Off ProxyPass /webmail/ http://mail.mydomain.com/webmail/ <Location /webmail/> ProxyPassReverse / SetOutputFilter proxy-html RequestHeader unset Accept-Encoding ProxyHTMLExtended On ProxyHTMLURLMap / /webmail/ ProxyHTMLURLMap /webmail /webmail </Location> The ProxyHTML stuff is optional, it doesn't appear to affect anything. Clients access webmail via the URL http://www.mydomain.com/webmail. I also have a mod_rewrite rule: RewriteRule ^/webmail$ webmail/ [R] to handle the "trailing slash problem." Any suggestions are greatly appreciated.
