What is a proxy server and how is it related to HTTP?

A proxy server lessens network traffic by rejecting unwanted requests, forwarding requests to balance and optimize server workload, and fulfilling requests by serving data from cache rather than unnecessarily contacting the true destination server. HTTP Server has proxy server capabilities built in.

How does socks5 proxy work?

A SOCKS proxy server creates a Transmission Control Protocol (TCP) connection to another server behind the firewall on the client’s behalf, then exchanges network packets between the client and the actual server. Therefore, a SOCKS proxy relays a user’s TCP and User Datagram Protocol (UDP) session over firewall.

Why do we need TCP proxy?

A TCP proxy is a server that acts as an intermediary between a client and the destination server. Clients establish connections to the TCP proxy server, which then establishes a connection to the destination server. TCP proxy supports Window Scale (WS) option that are carried by SYN and SYN ACK packets.

HTTP proxy requests: The first packet is sent to the proxy. The requested URI shows the complete URL (host + path). The second packet is sent from the proxy to the final destination. And since it is a “real” proxy, both packets are inside its own TCP connection with different source addresses as well.

How are HTTP proxy requests different from http direct requests?

Direct HTTP requests: Destination IP is the HTTP server and the requested URI shows only the path behind the domain. Preceding is a DNS request from the client to its configured recursive DNS server. HTTP proxy requests: The first packet is sent to the proxy. The requested URI shows the complete URL (host + path).
