i think it could help my pc resources a lot. if i understood correctlly, it works only for browser.
and in case you visit 100 websites+ (without restarting thread/browser), the cache you didnt save (or saved) really makes a difference in performance especially if its a lot of threads?
Correct, the network actions are related to the browser only. Denying the data you will not need, img or css for example will load the websites alot faster and will not save the information for future usages.
