my uni group are working for a client, and we have a Heroku app set up to handle the server side of things. I'm currently working on an AJAX login function, but I am redirected automatically - and that's the problem: there isn't supposed to be any redirect. It's coming from Heroku, not our code.



Our Heroku as a REST API returns exclusively JSON perfectly fine, using the URL https://blah.herokuapp.com/ (200), until I send an AJAX request via JS or JQuery: it redirects to https://blah.heroku.app.com/ (301), which redirects to www.app.com (200).



When you try to access that second one with the extra ., it redirects straight to www.app.com, which is how I know that it's Heroku. Edit: I tested someone elses Heroku app, and it does the same thing when you add the extra ..



I'm at a loss as to why it redirects to the second one, or why Heroku redirects to a dodgy site. Any ideas?

  • Turns out that app.com is the top level domain. So the extra period is cutting off the heroku and appname. So that's how we end up at www.app.com.

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
