Wordpress uses a .htaccess file to rewrite all the URLs to look like “http://www.kingrosales.com/category/internet-marketing/” rather than “http://www.kingrosales.com/index.php?pageid=10″.

# BEGIN wordpress
<ifmodule mod_rewrite.c>
rewriteEngine On
rewriteBase /
rewriteCond %{REQUEST_FILENAME}!-f
rewriteCond %{REQUEST_FILENAME}!-d
rewriteRule . …
