Source IP based reverse proxy
Source IP based reverse proxy If you want to proxy some source IP ranges/subnets to one server and onther subnets to go to a different server, you can do this using mod_rewrite for proxying. You will have to setup a rewrite condition based on the source IP and a rewrite rule with the [P] flag. Something like this should work: RewriteCond %{REMOTE_ADDR} ^10.2. RewriteRule ^/(.*) http://old-app/$1 [P] ProxyPassReverse / http://serverA/ RewriteCond %{REMOTE_ADDR} ^10.3. RewriteRule ^/(.*) http://new-app/$1 [P] ProxyPassReverse / http://serverB/ One possible scenario for this if you want to migrate your users from server A to server B but you want to migrate one IP range at the time. If youre using Apache 2.4 or newer you can also achieve this with the following configuration: <If "-R 10.2.0.0/16"> ProxyPassReverse / /http://serverA/ </If> <ElseIf "-R 10.3.0.0/16"> ProxyPassReverse / /http://serverB/ </ElseIf> <Else> ProxyPassReverse ...
