We're using the AuthCAS module for authentication with WeBWorK 2.18. When authenticated the ticket is always part of the query string in the browser URL, so if you're on the course administration page the URL is always something like https://webwork.yourschool.edu/webwork2/admin?ticket=ST-<long alphanumeric string>. This means you can't bookmark pages, and if you reload a page you get the following warning:
Warning: There may be something wrong with this question. Please inform your instructor including the warning messages below.
Failed to validate Service Ticket ST<long alphanumeric string>
Failed to validate Service Ticket ST<long alphanumeric string>
Is there some way to eliminate this behavior?
Thanks,
Charles
