The Apache module mod_rewrite provides a powerful way to do URL manipulations. With it you can do nearly all types of URL manipulations. The price you have to pay is to accept complexity, because mod_rewrite's major drawback is that it is not easy to understand and use for the beginner.

Apache supports an unlimited number of rules and an unlimited number of conditions for each rule to provide a really flexible and powerful URL manipulation mechanism. The URL manipulations can depend on various tests, for instance server variables, environment variables, HTTP headers, time stamps and even external database lookups in various formats can be used to achieve a really granular URL matching.

These modes an be set for both on server end (httpd.conf) and per-directory context (.htaccess).

I am giving simple example to make SEO friendly URL by rewriting:-

Suppose you have URL like this:-

http://www.yourdomain.dom/resources/index.php?c=3

and you want to make it search engine friendly, then you need to write .htaccess file and upload in the web site as belwo:-

RewriteEngine On
RewriteRule ^resources/advertising(.*)$ index.php?c=3 [L,NC]

and it will write it as belwo:-

http://www.yourdomain.dom/resources/advertising/
