So I finally managed to get my script to login to a website and download a file... however, in some instances I will have a url like "http://www.test.com/index.php?act=Attach&type=post&id=3345".  Firefox finds the filename ok... so I should be able to.
I am unable to find the "Content-Disposition" header via something like remotefile.info()['Content-Disposition']
Also, remotefile.geturl() returns the same url.
What am I missing?  How do I get the actual filename?  I would prefer using the built-in libraries.
It is the task of the remote server/Service to provide the content-disposition header.
There is nothing you can do unless the remote server/service is under your own control..
Using python (urllib) to download a file, how to get the real filename?
