My program allows users to create an account to login, etc. like most other programs. I am using the login routine supplied by rails. In my program I have an option to ''add funds'' to the account. When the user selects this option I ask them how much they want to pay, etc., I then take this info and the user is taken to an authorize.net payment page (I pass the data that Authorize.net needs in order to processs the order). If everything goes well, the user gets charged and Authorize.net is instructed to call one of my controllers. It calls the controller successfully -- there''s only one problem. The session and cookies that were created have suddenly disappeared so I can''t retrieve them and the login screen keeps appearing right after a successful (or unsuccessful) transaction. What did rails do with the session? Did leaving to another site and then returning ''destroy'' the sessions? Any advice or recommendations? (Please note that I am aware of the rails Authorize.net payment library. If you have any information regarding my ''bug'' above though I would sincerely appreciate it rather than just recommending I use the Authorize.net lib. thanks) -- Posted via http://www.ruby-forum.com/.
