Please take a moment to do a bit more reading about how browser caching
works:
-
https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching
You cannot directly control what the browser chooses to cache but you can
use mod_expiry and friendly-reusable URLs (like XYZ tiles) to help in that
cause. Repetitive WMS requests will be caught by the cache but it's much
harder to get a hit as it will change when the screen size, resolution, or
small shifts in locations differ.
To directly answer your questions:
1. No, you are not correct. The browser CAN cache those requests.
2. Yes, the browser will cache those images.
Cheers.
