Ok I have been able to get this worked but what I want do is I am trying to have two of my domain names pointed to a main domain lets say main.com, and when some one comming from xxx.com then all the links should be like xxx.com so I have been able to covert all the other links work like this with $vboptions[forumhome] , But for this one I created it like

$supportURL = str_replace('http://', 'http://support', $vbulletin->options['forumhome']);

$supportURL = str_replace('http://www.', 'http://support', $vbulletin->options['forumhome']);

But its returning like this http://www.xxx.com not like http://support.xxx.com

How to correct this?
