What is a proxy?
In: Technology
A proxy server is a network service that represents you in the internet. a device behind a proxy doesn’t (usually) communicate directly with the internet. so a host says „hey i want google“ and the proxy takes this request and presents you the google page.
In the beginning of dial up, and expensive data plans, the proxy server also cached each page. so if someone already visited microsoft updates, the would be cached and sent at lan speeds to your pc. Thus saving a ton of bandwidth! since https is widely adopted this is a whole lot more complicated.
