that doc does not exist any longer - could this be the information you originally linked?

If the host page headers are not correctly set, some browsers might cache the response, which can result in the host page not properly reloading when the user navigates to it...
To prevent this, at the very least, set the following headers on the host page.

Cache-Control: no-cache, no-store
Expires: -1
Pragma: no-cache
Other headers, such as Date and Vary are useful as well.

Yes, that's it.
