I am trying to make MvcForum a child application of my main MVC5 site. I have set its folder (/forum) as an actual application in IIS settings, and it seems to run fine with one exception:
I can't log in. Viewing the resources in Chrome dev tools shows me cookies being set, but the page always returns as if not logged in. What am I doing wrong? My main site logs in perfectly (using the Identity method in the default MVC5 template) but the forum doesn't.
