What is servlet:Servlet is a server-side java application.It can directly output information like jsp The servlet class must inherit the HttpServlet class. Otherwise, it cannot be called serlvet. The servlet class is a java class, but it has its own rules.Servlet must be registered in the

developers are most concerned about the problem of the program code, the page code basically does not need too much adjustment. With the development of technology, including DHTML, JavaScript, the page can be designed very complex, and due to the emergence of various CGI libraries, the program code is much easier. In this way, every time the page code is adjusted, the CGI program needs to be changed so that in the end of the CGI program debugging, th

HTML is still returned from the server side, the code on the browser can embed the HTML fragment into the current page. This means that the response of the Web application can be faster, when we actually replace the Web page with a Web application. Google's Gmail and Google Maps were the killer products of Ajax at the time. Then local refreshes with Ajax are spr

I. Introduction With AJAX technology, a browser page can send data requests to the server in the background while the front-end user interfaces remain active. This leads to a typical problem-the previous two activities simultaneously access common JavaScript and DOM data structures. Traditionally, the solution to this concurrent programming problem is not provided using JavaScript. This article describes an improved and proven mutex mechanism-it can i

Recently just finished reading Hae's "large Web site technology architecture-core Principles and case analysis", the key content of each chapter made some notes, in order to deepen the impression and future review.First, the characteristics of large-scale website software systemhigh concurrency, large flow: need to face high concurrent users, large traffic access. High Availability: system 7x24 Hour service

Since the invention of the computer, it is natural to print the content in the computer. This is especially true after the Internet era. However, it is not easy to realize the web printing function perfectly, and it is impossible to solve this problem completely. Remember that Tian rongju (Note:Tian rongju is currently the senior vice president and chief technology officer of Kingdee group. He talked to me

, but because of MS a large environmental problem so in some ways back to make it shrink in a small frame, if it can better jump out of this framework, I think by it now the basis will be no comparable. ASP is more precise is a middleware, this middleware will transfer the request of the Web into an interpreter, in this interpreter will all the ASP's script analysis, then carry out, and then in this middleware to create a new COM object, Manipulate an

process is unidirectional, as shown in.The general purpose of one-way hash encryption is the encryption of the user's password, so that the password is not reversible to the database, even if the database information leaks, the attacker can not know what the original password is.The common one-way hashing algorithm has MD5, SHA and so on.5.2 Symmetric encryptionThat is, both encryption and decryption use the same key, as shown in:The commonly used symmetric encryption algorithm has DES algorith

In the field of design, many people agree that the design should be simplified so that the corresponding work can play a better role, the design is only to enhance the visual means. With the development of Web site construction technology, the realization of complex functions in the Web page is no longer difficult, Web
