Well, in the browser the "window.location" object has a "pathname" property, which is (I think) what you're asking for. There are other properties for the "protocol", "host", "port", etc: http://msdn.microsoft.com/en-us/library/ms952653.aspx

Now, that's the local path for the page you're working from; in other words, that's not a general-purpose way to get the local path for any old URL floating around in space.
