Hi all, I'm trying to track down an intermittant problem with our apache servers where they intermittantly serve 502 responses when I believe they should be able to contact the server. Our situation is that we have apache sitting in front of BEA Weblogic (both 8.1 and 9.1). We are simply using apache for some re-writes and a few other bits and pieces and generally it works very well. However we frequently experience bouts of 502s being served, when I believe that WL is available to serve requests.
We're running 2.0.46 on redhat and have attempted to fix this problem by turning off keepalives by setting force-proxy-request and proxy-nokeepalive. However I'm not 100% sure what I've done is working. As we have several virtual hosts and they all experience this problem I want to apply this globally and so have created a file /etc/httpd/conf.d/__proxy_1_0.conf which is then included in the configuration and used for each virtual host (I hope). Here's some details on our config: [EMAIL PROTECTED] conf.d]$ ll total 20 -rw-r--r-- 1 bea bea 460 Oct 19 16:40 access.conf -rw-rw-r-- 1 bea bea 139 Oct 20 14:17 __proxy_1_0.conf -rw-r--r-- 1 bea bea 355 Feb 20 11:10 schemas.autodesa.org.conf -rw-r--r-- 1 bea bea 657 Feb 20 11:10 track.toyota.com.au.conf -rw-r--r-- 1 bea bea 2076 Feb 20 11:10 _webservices.toyota.com.au.conf [EMAIL PROTECTED] conf.d]$ cat __proxy_1_0.conf # See http://issues.apache.org/bugzilla/show_bug.cgi?id=37770 for reference SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 The other config files are all pretty straight-forward virtual hosts. Am I wrong in thinking that this proxy config will be included and used as I'm hoping? Would I be better off renaming it to proxy.incl and including it in each virtual host itself? Looking at http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#envsettings it would seem to suggest that the SetEnv directives need to be inside the same location block as the ProxyPass directive however the SetEnv docs ( http://httpd.apache.org/docs/2.0/mod/mod_env.html#setenv) say it can be applied at various levels. I'm assuming that applying it at the top level will cascade down, is this the case? For the record, my location blocks look like: <Location /ibus> ProxyPass http://localhost:7501/ibus ProxyPassReverse http://localhost:7501/ibus Allow from All </Location> Any suggestions or pointers would be gratefully appreciated. cheers dim --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
