calling a $_SERVER['REQUEST_URI'] within a template

[bleavitt]

I'm in the process of migrating from 3.0 to 4.0 setup of vBulletin. I've noticed that in 4.0, php tags do not work within the template files themselves. Hence it would seem that something like {vb:var variable_name} is the format I need to employ for what I'm trying to accomplish. I've got a custom login redirect that I'm working to implement. To do so, I need to call the equivalent of $_SERVER['REQUEST_URI'] within the template.

My question is does such a predefined variable exist? If not, is there an easy way to create this variable? Basically, what I am doing is sending a call to a login page which needs to know which page the user was on when the call was initiated.

I've already spent several hours searching the forums and Google for a solution to no avail. I've also read through the Template Tags and Languages and Phrases section without much success.

I'm completely new to the vBulletin environment, so any help would be appreciated.
