Maybe you can find the filename in the HTTP header. Many scripts use
some kind of header like this to identify the file:

Content-Disposition: atachment; filename="name_of_the_real_file"
Content-Type: "content_type"
Content-Length: file_size
Pragma: no-cache
Expires: 0

Keep in mind, that not every browser can handle this. (For example Opera
can't but Explorer, Mozilla/Netscape, Konqueror, etc can.)
