redirect http://www.site.com to http://site.com

[Chew]

I know I saw a php script to do this somewhere, however my brain is fried at 5:30am and I have searched everywhere.

I use cookies that require my visitors to use http://site.com however a large majority of the internet population uses www.site.com still.

How do I go about redirecting them to http://site.com if they came in from http://www.site.com?

Thanks in advance!

Use the following in a php script:

<?php 

$server = getenv("HTTP_HOST"); 

if (ereg("^www.", $server)) { 
    // Assume www. has been entered 
    Header ("Location: http://".$server."/"); 
    Exit; 
     
} 

?>

That should do what you're trying to do.

Cheers,

You can also use mod_rewrite in your .htaccess file. Put it inside your public_html directory in order for the changes to effect all files/directories.

The code below is for doing the opposite to what you wish to do (ie going from no www to a url with www). I'm not a mod_rewrite expert so I'm not sure how to reverse the effect of it:

RewriteEngine On
Options +FollowSymlinks
RewriteCond %{HTTP_HOST} ^domain\.com
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=permanent,L]

Replace domain and .com as necessary.

Thanks tons to the both of you.

Gonna have to figure out which one works best for my usage

I think if you can work out how to reverse the mod_rewrite option, it will be better because I think it will forward http://www.site.com/filename to http://site.com/filename.

I'm pretty sure the php method will only forward it to the main page on your site.

Here's a nice page to explain how to use RewriteEngine.

Just found this and thought i'd have to butt in and ressurrect this puppy...


Redirects are ok but you should really be doing a 301 Redirect for SEM sake, and thus google will love you as will yahoo, etc.

In php:

<?php
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://new-url.com" );
?>

Chew,

This doesn't make sense, because as I understand it cookies registered as being from site.com will also get sent to www.site.com and also to anything.site.com. Have you checked to see whether your cookies are getting there anyway?
