When page is loaded first time, it displays as blank page and if we press CTRL+F5, it is loaded. This happens when we enable Output Cache Module. We have login and logout features on the website and we do have cookies setup for 1 month. Due to Output Cache Module, the login and logout links are not changed dynamically as per the user's login/logout status. We use Orchard 1.7. Can anyone give me the solution for this issue?
