1. lighttpd LIGHTTPD is a feature with very low memory overhead, low CPU usage, good performance, and rich modules. LIGHTTPD is one of the best in many opensource lightweight Web servers. Support FastCGI, CGI, Auth, output compression (outputs compress), URL rewriting, alias and other important functions. LIGHTTPD uses fastcgi to run PHP, which uses very few PHP processes to respond to a large amount of co

The function principle of HTTP protocol WWW is an application system with Internet as transmission medium, the most basic transmission unit of WWW is Web page. The work of WWW is based on the client/server computing model, consisting of a Web browser (client) and a Web server (server), which communicates with a Hypertext Transfer Protocol (HTTP). The HTTP protoco

PHP allows multiple web servers to share SESSION data (write session data to mysql database) I. websites with a slightly larger problem generally have several servers, each of which runs modules with different functions, different second-level domain names are used, while the user system of a website with a strong integrity is unified, that is, a set of user name

Many of the development involved in the user's session validation is very reserved questions, the problem is more interesting, summed up a number of programs, only for reference. 　　 [question raised] In order to meet a large enough application to meet more customers, so we set up the N Web server (n>=2), in the case of multiple Web servers, we will involve a pr

Introduction to HTTP protocol Hypertext Transfer Protocol (HTTP) is located in the TCP/IP protocol application layer, is the most well-known protocol, but also one of the most core protocols in the interconnection network, the same, HTTP is based on C/s or B + + model implementation. In fact, the browsers we use, such as Netscape or IE, are the clients that implement the HTTP protocol, and some common Web server software such as Apache, IIS, and ipla

this point the user will see the word "End of message" in the browser. The whole process is over.3.CGI IntroductionIntroduction to CGI:=====================First, the concept: Public Gateway Interface CGI (Common gatewayinterface) is one of the most important technologies in WWW technology, which has irreplaceable important position. CGI is an interface standard between an external application (CGI program) and a Web server, and is a discipline for p

Preface: After a brief introduction to the network layer protocol and HTTP protocol in the previous topic, I believe that you have a general understanding of the protocols in the network. This topic will define a Web server for the HTTP protocol, you can view the desired webpage by entering a URL in the browser. In this process, the browser is only a client.Program) Send user requests to the server through the HTTP protocol. The server receives the

Recently and a few friends, chatting to concurrency and server stress issues. Many friends, do not know how to calculate concurrency?　How many servers are appropriate to deploy? So, let's talk about it today. PV and concurrency, as well as how to calculate the number of Web servers. These are their own ideas plus some online summary, if not, welcome to shoot bric

this tested storage system. What I want to do is to make this system into a fault-tolerant Web server cluster. Raspberry Pi's CPU processing speed and memory resources are not very high. Fortunately, it is more than enough to deal with a static Web server. I deliberately made this example very simple, because I think if you can flat this simple example, you can also deal with complicated problems.Install N
