I have a Flex application that uploads a file to the server and works great by itself. However, when I team it up with JCIFS for SSO it stops working. What is strange is that loading images and any other HTTP requests seem to work just fine, but when I do a URLRequest to upload the file it re-challenges the browser for authentication and I get a prompt to log-in.
Is there something I can do to make this file upload work the same way all the other requests work so I don't get challenged after I've technically already been authenticated? I've verified the headers on the server and IE gets the JSESSIONID and Firefox does not, but both still prompt for authentication at upload time. Help is greatly appreciated.
