Understanding the differences between SOCKS and HTTP proxies is crucial for optimizing your online activities, whether you are a tech-savvy individual, a modern internet user, or a business owner. When using proxy IPs, it is essential to first understand the differences between these two protocols. 1. Understanding HTTP Proxies HTTP (Hypertext Transfer Protocol) proxies are … Read more
Click the above“blue text” to follow us I just returned from a meeting with my boss, and he immediately asked, “Why is our app so slow? Especially when the network is unstable, it’s so laggy that it makes people want to throw their phones!” I thought to myself, isn’t this just the old problem of … Read more
In modern software development, network communication is an indispensable part, especially when building distributed systems, microservices architectures, and various client-server applications. Apache HttpClient, as a powerful and mature Java library, excels in handling HTTP requests and responses, and is widely used in numerous practical projects. Apache HttpClient supports various HTTP request methods, including GET, POST, … Read more
What are the Differences Between HTTP/1.0 and HTTP/2.0? Key Points This analysis focuses on the differences between the two protocols from the perspectives of connection methods, data transmission formats, and header compression. Connection Methods HTTP/1.0 Short Connections: Each request requires a separate TCP connection, which is closed immediately after the request is completed. Head-of-Line Blocking: … Read more
Introduction Continuing from the previous article, where we attempted to write a Hello World program in Prolog, we learned about the basic structure and execution of Prolog programs. In this article, we will build a simple HTTP server based on <span>hello_world.pl</span>. Starting the HTTP Server Using the built-in library of SWI-Prolog, it is easy to … Read more
Introduction “MQTT (Message Queuing Telemetry Transport)” is a lightweight messaging protocol commonly used for communication in the Internet of Things (IoT) and sensor networks. It is designed to transmit data in low-bandwidth, unstable, or high-latency network environments, making it particularly suitable for communication between connected devices, especially in resource-constrained environments. This article will briefly introduce … Read more
In previous articles, we introduced MQTT and UART. So what do we get when we combine them? As engineers, we often encounter the following scenario: on-site, we need to connect a computer to a PLC or control device via a serial port, and the PC reads or writes data to the on-site device using a … Read more
