Access doc from web

I know how to open a document from the web like so.

VB Code:

Set doc1 = objWord.Documents.Open("http://my.site.com/path/to.doc")

My problem is I need a way to use this document in a method call that needs the filename in the form of a string.

Of course, the first thing I tried was putting in the entire URL as a string, but it doesn't seem to like the 'http://' reference.

I also tried referencing the document object that I already opened. If I use 'doc1.FullName', it throws an error saying, "The document name or path is not valid". Is there a way to use the object that has already been opened? Maybe point to whereever the temporary file is being stored?

Any help would be greatly appreciated.

FYI. I'm trying to use either Word's '.Compare' or '.Merge' method to difference 2 documents over the web without saving them locally.
