In the traditional sense, proxy server is the server between the user computer network and the Internet, its function is to proxy network users to obtain network information, it can be understood as a transit point for network information. If the Web browser is configured to use a proxy server, all requests will only be forwarded through the
Recently looking at a book on Javaweb implementation of the Web site distributed architecture, it mentions that through load balancing, you can avoid issues such as server paralysis caused by massive access or the inability of users to access due to a single server failure. There are many ways to achieve load balancing, such as: F5 server or software, such as LVS (Linux virtual Server) or Nginx. I chose to use Nginx to practice load balancing.

Analysis of Reverse ProxyThe reverse proxy method refers to a proxy server that accepts connection requests on the Internet, then forwards the request to a server on the internal network and returns the results from the server to the client requesting the connection on the Internet,

Proxy servers are widely used to connect LAN hosts to the Internet. Using proxy to access the Internet can save scarce IP Address Resources and block access from external hosts to internal hosts, protects Intranet hosts from attacks on external hosts. However, if you want to allow hosts on the Internet to access host resources on the Intranet (for example, web sites) and protect hosts on the Intranet from a

For a Web site with a daily visit to millions, the speed is quickly becoming a bottleneck. In addition to optimizing the application of the content publishing system itself, if you can not need real-time update of the dynamic page output to the static page to publish, the speed of the promotion will be significant, because a dynamic page speed is often slower than static pages 2-10 times, and static Web content if can be cached in memory, The speed of access will be even more
The usual proxy server, which is used only for proxy internal network connection requests to the Internet, the client must specify a proxy server and send the HTTP request that was intended to be sent directly to the Web server to the proxy server to initiate a request to the Web server on the Internet by the

But there's no Readme page on the ooxx.me.
He was secretly taking it back from another server, and then spit it out to the user as his content.

The static and dynamic separation in this paper is mainly realized by Nginx+tomcat, in which the nginx handles the images, HTML, JS, CSS and so on, and Tomcat handles the dynamic requests such as JSP and servlet.

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load balancer and executes Server Load balancer tasks based on informa
As mentioned earlier, using a proxy server can forward requests to an internal Web server, and using this acceleration pattern can obviously improve the access speed of static Web pages. However, it is also possible to consider a technique that uses a proxy server to forward requests evenly to multiple Web servers to achieve load balancing purposes.
