Apache mod_rewrite
All examples need this code:
RewriteEngine On
Rewrite conditions are cumulative, and will redirect when a RewriteRule is given.
Rewrite conditions also execute in listed order, so if the first one matches it will redirect, and the second one won't be read.
You can use perl regular expressions.
Examples
Match URLs that are not ''server-status'' or ''server-info''
RewriteCond %{REQUEST_URI} !^/server-(status|info)/?$
Add a new environment variable
You can access this in PHP through the $_SERVER array.
RewriteCond %{REQUEST_URI} steve\.php$
RewriteRule . - [E=VARIABLE_NAME:variable_value,L]
