问题 I manage a ColdFusion-based website that recently migrated from CF 8 to CF 10. The site requires users to log in and keeps certain values in session variables, which are used throughout the site for verification, etc. Since the migration to CF 10, I have been having a lot of trouble with sessions not "sticking" from page to page, particularly after the login process.
