not a problem
 

This is strange to me. i was working on the header template, and i have a link to my external home page, but if i put www.x.com, it will redirect to www.x.com/forumdirectory/www.x.com

the link only seems to work properly if i put an http:// in front of it.

I find it very odd that it just assumes to forward all links to "forumdirectory/"

If a url doesn't start with http://... then it's relative to the current url (or to the one in the <base> tag if there is one). It's an html thing, not a vbulletin thing.
