Tabproxy works like an HTTP proxy in that it is a server that accepts requests from users and forwards those requests to other servers on the Internet. The proxy server can intercept, modify, or filter requests, as well as respond to client requests. Specifically, Tabproxy realizes the proxy function by receiving the user's request, establishing a connection with the target server, forwarding the request, letting the target server process the request, and then returning the response to the user. In this way, Tabproxy can help users achieve anonymous access and protect privacy security.
