How to force Turbo to only get data from his cache and not reloading from Server?

[kwemou]

Dear All,
I have an application where chat page when generated will stay the same unless somebody type some new message.

I want turbo to not fetch that page from server (after I clicked on a link) if the page was already loaded in the Browser cache.
To reload the chat Page from server, I want to provide a special "Reload" button.
This feature will reduce traffic with my server for many use cases.

Is this possible with Turbo?
Thank you
Best regards
