web application – How do I set up a specific page in the app that will not save cache files?

My site has a live broadcast embedded from another site.
[Live broadcast on the site[!
And the problem starts with the app,
That if I set to save cache files, then the live broadcast does not work because the page has already been saved on the phone and is not renewable.
And if I set it to not save cache files, then the live broadcast does work, but the whole app gets very slow.

Do you have a code that I can put on the live broadcast page, clear all the cache files automatically and refresh the page?
