Recently, I researched monitoring group messages on Telegram and planned to extract key information from the received messages to save it to my local database. I utilized the code from the open-source repository https://github.com/Riniba/TelegramMonitor?tab=readme-ov-file, adding HTTP requests to it. First, open the source code. Right-click to open the Manage NuGet Packages and add two packages. … Read more
Understanding Packet Loss Packet loss, as the name suggests, refers to data packets that are “lost” during network transmission and fail to reach their destination. The HTTP protocol runs on the TCP/IP protocol stack, and packet loss can occur at the network layer, such as when a router is overwhelmed and drops packets, or at … Read more

1. Introduction to HTTP HTTP (Hypertext Transfer Protocol) is an application layer protocol used for transmitting hypertext (such as HTML files) over the network. It is based on the TCP/IP protocol and serves as the foundation for data communication on the World Wide Web. Below, we will detail HTTP from multiple aspects. 2. Development History … Read more
In internet communication, TCP (Transmission Control Protocol) and HTTP (Hypertext Transfer Protocol) are both key protocols, but their roles and applicable scenarios are completely different. Many people may be confused: 1. Since TCP can already transmit data, why do we need HTTP? 2. When should we use TCP directly, and when should we use HTTP? … Read more
