I would like to know is it possible to achieve with (my guess is) a proxy server to add some content to users response?
Let's say I would like to add a div
to each html document which is being opened by users of my local network. So what I'm looking for is some sort of a intermediary server. It might be just my imagination that something like this exists, but if it does could you tell me the technical name of the functionality that I'm looking for? Any free/open source solutions?
Greetings, and thank you for answers.
