[Httpd Wiki] Update of "RewriteFlags/P" by RichBowen

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The following page has been changed by RichBowen:
http://wiki.apache.org/httpd/RewriteFlags/P

New page:
The P flag causes the resulting URL to be requested by proxy, using mod_proxy. This allows for complex proxying of content to a variety of back-end servers. You do need to have mod_proxy installed in order to use the [P] flag.

{{{
RewriteEngine On
RewriteCond %{Request_URI} !^/images
RewriteCond %{Request_URI} !^/css
RewriteRule ^(.*)$ http://other.server.com:90$1 [P]
ProxyPassReverse / http://other.server.com:90/
}}}

The above ruleset causes all URLs, except those for the /images and /css directories, to be proxied through to another server, running on port 90. The ProxyPassReverse directive is to ensure that redirects returning from that server are correctly passed back to the client. (See [http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#proxypassreverse the ProxyPassReverse documentation] for more details.)

The more verbose [Proxy] syntax is also permitted.
