How does Socks5 work?

Question

C++ / C#

I'm trying to implement a Socks5 server, I can't figure out at what point the server returns the page to the user?
I read here : look on page 4 when you go to the incoming IP, I get what the north sends, after on page 5 I send where to connect to it and I correctly understood that I send him a response from the server (if there was originally a demand to receive the page, then I send the page ), did I get it right?

Answer 1

socks5 server does not "return the page", Socks5 server creates a connection to the server at the request of the client, and then maps all traffic between the client and the server. All data received from the client is redirected to the server and vice versa, while SOCKS5 does not care what application protocol is used, it can be anything, not necessarily HTTP, mapping occurs between two sockets.
