There’s a pretty hardcore open-source project on GitHub called “Network Proxies and VPN Applications Explained.”
If you regularly use Clash, Surge, V2Ray, or a VPN but have never really understood how proxies work behind the scenes, this documentation is well worth a read.
It starts with the fundamentals of proxies, tunnels, and VPNs, then goes on to explain network blocking mechanisms such as IP/port blocking, DNS poisoning, TCP RST, and SSL connection blocking. Many sections also include diagrams and real-world examples.
If you’re a beginner looking to learn the underlying principles of network proxies, bookmark it and work through it at your own pace. Read online: https://hoochanlon.github.io/fq-book/
