Hello, I'm working on a setup with the following structure, all the software is in the same server. Apache 2 server with mod_proxy, mod_rewrite and some others. An apacher conf file with 3 Virtualhosts of different domains for a rails app. Each virtual hosts has some rules to redirect petitions to a mongrel cluster (which is an http webserver oriented for rails app) I need to implement some auth based on ips, all 3 virtualhosts needs the same ips for auth. My problem cames when managing the ip list, there is a lot of editing when adding new ips, so i am looking for a way to centralize the list of ips and then use this list in all checks. I've been looking for using RewriteMap or something like this, but I have a little experience with apache. Each virtualhost file is almost identical except for some path names. Here is the config of one virtual host. <VirtualHost *:80> Servername my.example.com ServerAdmin my@xxxxxxxxxxx DocumentRoot /var/www/theapp/current/public/default <Directory "/var/www/theapp/current/public/default"> Options FollowSymLinks AllowOverride None Order Deny,Allow Deny from all Allow from x.x.x.x Allow from x.x.x.x Allow from x.x.x.x #. #. #. #Lot of allow rules for some ips </Directory> RewriteEngine On # Rewrite index to check for static RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ RewriteRule ^/$ /index.html [QSA] # Rewrite to check for Rails cached page RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ RewriteRule ^([^.]+)$ $1.html [QSA] # Peticiones de contenido din RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ [OR] RewriteCond %{REMOTE_ADDR} ^x.x.x.x$ RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L] # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.
