how do i get the http address?

[mostwanted]

i am trying to get a flash ".swf" file to set a variable for the url that the file is embedded on. i know there has to be a way! I am using the " this._url; " to get the url, but all it gives me is the url to that swf file. I want the entire page's address to be my variable, not the swf url. I am trying to send that variable over to a php page to write it to mysql, but i can't get it to give me the right variable.

lvOut.address = this._url; //this sends the variable to php

it does send the variable, but the variable is not the full url to the page it is loaded on, it is the url to the flash file


Please help!
