Browser should refresh cache only when necessary












0















I would like for the browser to behave in the following way when requesting an item from the server.


  • Browser checks its cache.

  • If the item is not there then request it from the server.

  • If the item is in cache then request its timestamp on the server.

  • If server timestamp is more recent than the cached timestamp then request item from server.

  • 5. Otherwise use cached item.


    • Is this behavior implemented in modern browsers? If so how do I request this behavior from the browser?

    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...
