There is an existing community post on this topic that recommends updating to Telligent 10.1 -> https://community.telligent.com/community/10/f/ask-the-community/1144789/stale-browser-cache-issue/1600504#1600504. This is not an option for us in the short term. Currently you cannot enter a Telligent Support ticket to discuss further - you get a Salesforce Supportdesk error when going to the help desk so I am starting another thread to get feedback.
But we are getting a ton of issues where Telligent is caching content and the rendering looks bad. We can't ask thousands of users to hit ctrl-F5 and our site is a public site.
Can you do something like setting cache-control with a value of 'max-age=43200' to force browsers to refresh every 12 hours. This can harm performance, but we have to do something to clean up the look and feel.
Any suggestions would be helpful.
Thanks,
Mitch
