Can someone explain what are HTTP proxies and how they work? or What are HTTP proxies and why would I

Thanks so much, everyone! This really clears things up. I tried KProxy like someone suggested, and it worked for accessing a geo-blocked site (cool!).

But now I’m curious—how do you tell if a proxy is safe to use? Like, are there red flags to watch for?

Also, is there a big speed difference between free and paid proxies?

Appreciate all the help!
