Apache mod_rewrite

mod_rewrite is an Apache module that contains the rewrite engine to rewrite URLs. This is a very handy tool that can interpret a URL request and rewrite it to any URL you like.

Some common uses include:

• Replacing long ugly URLs with shorter, user-friendly ones
• Preventing "hotlinking", so other sites can't steal your bandwidth
• Moving pages while keeping old links intact
