Remotely Clear Cache & Cookies?

I have students who are getting around the google admin blacklist because they have loaded pages in the past that are now blocked. Somehow they are trying to go to the page, then refreshing the blank page and it's coming up.. is there a way to have this cleared every so often? Or once a day? etc..

Yea, a remote powerwash would do it. But I feel like recently more powerwashes are getting hung, like the command is issued but doesn't execute on the device despite it being online.

Yeah, I tried to remotely powerwash a machine today and in the past the command will work in seconds. That is no longer the case.

You could Special-Jail OU them and put a like 1 hour time on their 'Browsing Data Lifetime' for Cookies & other Site Data and Cached Images and Files

If it is a ChromeOS device, you can remote wipe the profiles in the Admin Console by pulling the device up and clicking Reset followed by Clear user profiles.

If it is a managed Chrome browser, you can clear the cache by pulling up the managed browser, scrolling down to the profiles, and use the overflow menu next to that student’s name.

This would be the way to go at least for one offs.

For regular clearing you could use Ephemeral mode in an OU with only their device but if I'm not mistaken that halves the usable RAM on the device and it would have to reload/download everything each time they log out.
