is there a 'www' in the URL ?

[Ökii]

if($HTTP_SERVER_VARS['http_host'] !== 'www.domain.com')
{
$with_www = 'http://www.domain.com/'.$REQUEST_URI;
header("location: $with_www");
exit;
}

doesn't appear to be working.

Problem: cookies set at www.domain.com are not viewable by just domain.com.
Solution: quick test and if the URL doesn't have www in it, redirect to the same just with a www in it. eg
http://domain.com/blat.php --> http://www.domain.com/blat.php

Would mod_rewrite be a better method of accomplishing that?

Try


if($HTTP_SERVER_VARS['HTTP_HOST'] !== 'www.domain.com')


Although function names are case-insensitive, array keys aren't. So much for consistency in a language that aims for enterprise application. ;)

working perfectly now, thank you mordred :)
