Using iPad for multi-login web site
My university wants to use iPads to allow students to log into a web-based software system and submit electronic forms. Each student will have unique login information. In testing, we've had the students log out of the software after they are finished. But often, the next person who tries to login gets taken into the previous student's account. I tried turning on Private Browsing, but that hasn't prevented the problem. It doesn't seem like Guided Access will solve the problem.
How can I make sure the iPad and/or Safari clears the information from the website between users?
