I. Concepts of reverse proxy and Server Load balancer
Before understanding the concepts of reverse proxy and Server Load balancer, we must first understand the concept of a cluster. Simply put, a cluster is a server that does the same thing, such as a web cluster, database c
The Proxy server (agent) for TFS is used for continuous integration compilation and publishing, which is a very convenient and efficient release and testing speed for development, test teams and operations teams, and many companies and research and development teams use this technology extensively in their own research and development testing platform. In the process of deploying a TFS
To set up a proxy server, you must first know the proxy server address and port number, and then fill in the appropriate address and port number in the agent server settings bar of IE or NC. Suppose we have a proxy

The rapid development of INTERNET since the beginning of 1990s has rapidly changed people's lives and work. More and more companies have connected their local networks to the INTERNET. Of course, there are various ways to access the Internet.
Generally, individual users can connect to the Internet by buying a modem over a telephone line. Because of the large number of computers and the large demand for communications, the company generally uses leased line access methods. However, leased lines
Build Squid Proxy Server
Prepare the environment:
Client: 192.168.118.4
Squid Proxy Server: 192.168.118.3 (intranet IP) 1.1.1.1 (Internet IP)
Web server: 1.1.1.2
Goal: the client accesses the Web server through the Squid
In Java, the basic settings of the proxy server are completed by setting system properties. The proxy server is verified by setting the HTTP request header.The following is a simple example for your reference:
// Open an HTTP Connection Based on the URLHttpurlconnection con = (httpurlconnection) (new URL (URL). openco

The server on the Web is called Web server, but there is a different division of labor.
Nginx is often used to do static content services and proxy servers (not you FQ that agent), directly to the external request forwarding to the subsequent application services (Tomcat,django), Tomcat more used to do an application container, let Java Web App running inside th
Whenever we mention the reverse proxy, we usually think of Nginx, but today we temporarily ignore the well-known Nginx, using Nodejs, also a single-threaded, event-loop server brother.
