I've got 1 minute timeout in Deployment description for my sessions. I don't know why, but working under Stripes, i check if there is still an "user" attribute in session after 1 minute, and it is still there, so i can't redirect to login page.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
