That’s why JS gets hates on just as much as PHP, if not more so these days as JS is fuckin everywhere!

In the long long ago it was reasonably common (particularly on corporate or school/uni networks) to force all web traffic outbound from browsers through a proxy.

They’d then use these proxies to enforce policies (block sites basically) and often cache stuff too, important when internet connections sucked.

So generally proxies sit on the same network as the clients (browsers).

Reverse proxies sit on the same network as the servers.
