http:// vs www.?

[OS,]

Hi each time i enter my domain www.mydomain.com it remains to be www.mydomain.com as well as other sub domains sections. But if i try to enter my forum www.mydomain.com/forum then it changes to http://mydomain.com/forum missing out the www. what could possibly be wrong here?

Cheers thanks!

Perhaps your host or your own .htaccess is set to mod_rewrite www. to just the domain, but doesn't work on the forum/ dir? Or your forum path is set to that url so all the forum urls have www in them?

Here's an example of a .htaccess file that forces index.php to go to just the / at the end, and it forces www. to the url if it isn't. (set your forum Admin Control Panel > vBulletin Options > vBulletin Options > Site URL etc options to have www. in it.)

the .htaccess goes into your public_html/ dir (MAKE BACKUP if you already use a .htaccess file! - or rather merge it)
