Apache: redirect subfolder to another IP in the LAN
I have webserver1 behind a router currently serving all http traffic to mydomain.com. I just added webserver2, and want to redirect mydomain.com/server2 traffic to that box. To the user, the redirect should be unnoticed (i.e. the URL should just be mydomain.com/server2, and the redirection happens behind the scenes). How do I set this up in the apache configuration of webserver1 (I'm assuming webserver2's config needs to do nothing special)?
I've tried the advice given here, using mod_rewrite, but it didn't seem to do the trick:
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/server2/
RewriteRule ^/$ http://192.168.1.102/ [P,L]
In case it is relevant, webserver1 is hosting a django app using mod_wsgi, with a few other apps that get redirected away. Here is the virtualhost conf:
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName www.mydomain.com
ServerAlias 127.0.0.1
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/server2/
RewriteRule ^/$ http://192.168.1.102 [P,L]

Thanks in advance.
Mod_Rewrite is more flexible than mod_proxy. Uncomment the load line for it.
Simple comparison here http://www.wellho.net/mouth/1376_Choosing-between-mod-proxy-and-mod-rewrite.html
<VirtualHost *:80>
RewriteEngine on
# just in case (don't want to accidentally expose all the internal servers) !
ProxyRequests off
# define a log file
RewriteLog /var/log/apache/server2.rewrite.log
RewriteLogLevel 1
# add the tailing / if not there
RewriteRule ^/server2$ http://www.mydomain.com/server2/ [R] [L]
# proxy the request to internal url
RewriteRule ^/server2/(.*) http://192.168.1.102/$1 [P]
