Typically, most Web sites are designed to provide instant information access to visitors in the most acceptable way. In the past few years, the increasing number of hackers, viruses and worms security problems have seriously affected the accessibility of the site, although the Apache server is often the target of attackers, but Microsoft's Internet Information Services (IIS) Web server is the real target. H

method After a user logs on to the client, the website domain name, user name, password, token, and session validity period are all written into the client's cookie in the form of cookies, when a user switches from a Web server to another server, our program actively checks the cookie information of the client and then provides the corresponding service. of cour

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

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

Background:Our server environment, is the ESX server, which ran dozens of virtual servers. Most of them are virtual Windows servers, and then each application will have several app servers and then install WebSphere to build cluster to support the Web server, both IBM HTTP server and IIS.The environment is like this, t

home directory and its subdirectories are automatically open to site visitors. Visitors can view the file if they know the correct path and file name of the file they want to access, even if there is no link to those files in the home page. Therefore, save the files that you need to view only to the home directory or subdirectories. Each Web site must have a home directory, and access to the

most common problem is that the file name in the request is incorrectly spelled, so the server cannot find the file. In this case, the server will send a status code --- 404 to the customer. (5) close the file and network connection and end the session. When the file has been mailed or the error has been sent,The Web server ends the entire session. It closes the opened requested file, closes the networ

Windows Component. In the pop-up dialog box, select Internet Information Services (IIS). Then click OK to install it. The erection of Web sites You may have seen the "Default Web Site" option in the above image, you can either modify the default Web site for your new site, or rename a new Web site by clicking the righ

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

present, another kind of webserver has emerged, which is superior in terms of concurrency, called asynchronous servers Asynchronous Server. The most famous ones are nginx and Lighttpd. The so-called Asynchronous Server is the event-driven in the event-driven mode. In addition to the user's concurrent requests, only one or several threads are required. Therefore, system resources are very small. These are also called lightweight

Web|web Service |web Server | security | Attack Run Nmap Search the entire network can list all known servers within the domain. In addition, you can view DNS to see what the server administrator has set for this domain. Then use the previous Example.server field: # nslookup The command "set Ty

the paging file of an NT Server to multiple physical disks, note that multiple "physical disks" are not available on multiple partitions. In addition, do not put the page Exchange file In the same partition as the Windows NT boot zone C. Using disk mirroring or disk stripe sets can improve disk read performance D. It is best to store all the data in a separate partition. Then run the Disk Defragmenter on a regular basis to ensure that there is no fragmentation in the partition where the

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

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

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

improve the performance of IIS B. You can distribute the paging file of an NT Server to multiple physical disks, note that multiple "physical disks" are not available on multiple partitions. In addition, do not put the page Exchange file In the same partition as the Windows NT boot zone C. Using disk mirroring or disk stripe sets can improve disk read performance D. It is best to store all the data in a separate partition. Then run the Disk Defragmenter on a regular basis to ensure that there

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

accessed to the server, and then access the virtual directory to visit the specific Web pageThe first way to publish a Web site to Tomcat is because the virtual directory is a directory that does not actually exist because the directory is simply mapped to the corresponding directory.The first configuration of Tomcat/conf/server.xmlThe second configuration of Tomact/conf/catalina (engine)/host directory/xx

Web server unexpected, such as encountering network virus or Trojan attack, server host hardware damage, etc., to the fastest time in the Web server to restore the working state of normal, the most effective way is to restore the previous backup of the good Web server data directly restore, However, this method requires us to do backup work in advance on the impo
