Parsing In URL's

[Cloud Strife]

Hiya, could someone help me with this, basically I want my vbulletin to parse urls like this,

http://www.yahoo.com*/hello.html

etc... This way it will stop my board being the refferer. I tried other ways by editing th functions.php and the url comes out like this

-http://www.yahoo.com/hello.html

and it works in IE browser, but in opera, it doesnt and has

http://myboardurl.com-http://www.yahoo.com/hello.html

Could anyone help me with this??

Im guessing we will need a list of different endings like .com , .net, .tv etc

Oh and it would be nice if when specifying my own boards url it will parse it without the *

Thanks
