Htaccess tunnel to local server on another port?

  • 772

Is it possible to have 2 web servers running on the same box with different ports and then use htaccess to tunnel traffic from 1 server to another based on a rewritecond? Basically when a certain condition is met I want the request to be handled by my other web server and I don't want to return a moved response.

    Yes, it's possible. If the first server is Apache, you can use it as a reverse proxy using mod_proxy to do this. 

    ProxyPass /abc http://second-web-server.yourdomain.com/def
ProxyPassReverse /abc http://second-web-server.yourdomain.com/def

    http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#proxypass

    If your proxy requirement is more complex, you can also tell mod_rewrite to send the substitution part of the rewrite rule to mod_proxy with the "P" flag:

    RewriteRule ^/abc$ http://second-web-server.yourdomain.com/def [P]

    It appears (I'm not familiar with litespeed) that the litespeed rewrite engine is identical to Apache:

    http://www.litespeedtech.com/docs/webserver/config/rewrite/

    So to test for the absence of a cookie, you'd use a Rewrite rule like so:

    RewriteCond %{HTTP_COOKIE}       !^Your_Cookie_Name$
RewriteRule ^/(.*)               http://second-web-server.yourdomain.com/$1 [p]

    There's an example of litespeed rewrite+proxy here:
