Redirect 301 /old/file.html http://www.askapache.com/new/file.html

301 Redirect Entire Directory

RedirectMatch 301 /blog(.*) http://www.askapache.com/$1

301 Redirects using mod_rewrite - These are done in the .htaccess file.

For these to work the mod_rewrite engine must be on. It can be turned on by add the follwing line before your rewrite rules. Rewrite base is only really required if your site is in a sub folder.

RewriteEngine On
RewriteBase /

RewriteRule .* http://www.askapache.com/$1 [R=301,L]
RewriteRule ^(.*)\.html([^c]+)comment-(.+)$ http://www.askapache.com/$1.html#comment-$3 [R=301,L,NE]

How to 301 Redirect a non WWW to a WWW Domain

RewriteRule ^(.*)$ http://www.yourhost.com/$1 [L,R=301]

PHP Redirect

If you want a PHP redirect script that redirects visitors from a page to a specific URL then this is it. It sends the user from one web page to a different web page address. It is a good alternative to using the meta tag http-equiv option.

Put the following code in to a php file

Example 1

Example 2

NB: Be sure that you do not have any text sent to the browser before this code, or it will not work. Your safest bet is to simply remove all content from the page but the redirect code.
