Hi... Thank you for Axel and Neil for answering my question. I understand it won't be a good idea to pass the proxy server ip address/host name through parameter. Fortunately, this is only used for internal access only. My proxy server won't be connected to internet. The reason is I do have more than 20 internal web servers. For each web server, it doesn't have static IP. It can be change dynamically. The ip address/hostname for each of my internal web server I get it through parameter in the url. Any idea? Axel did mention in his post, I may be able to use RewriteMap. I will google it. Thank you Pdt Neil A.

Stick to mod_rewrite and you should be fine: >>> >>> RewriteRule ^/testing/(.*)$ http://myserverB/$1 [P,L] >>> RewriteRule ^/(.*)$ http://myserverA/$1 [P] >>> ProxyPassReverse /testing http://myserverB/ >>> >>> You can include: >>> >>> RewriteRule ^/testing$ /testing/ [R,L] >>> >>> before the above if you want to handle a missing trailing slash. > > > -- > Neil Hillard neil.hillard@xxxxxxxxxxxxxxxxxx > AgustaWestland http://www.whl.co.uk/ > > Disclaimer: This message does not necessarily reflect the > views of Westland Helicopters Ltd. > > --------------------------------------------------------------------- > The official User-To-User support forum of the Apache HTTP Server Project. > See <URL:http://httpd.apache.org/userslist.html> for more info. > To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx > " from the digest: users-digest-unsubscribe@xxxxxxxxxxxxxxxx > For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx > > > -- View this message in context: http://www.nabble.com/Apache-mod_rewrite-mod_proxy-conflict--tp14251664p14292649.html Sent from the Apache HTTP Server - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
