Summary of ASP advantages and JSP advantages

Brief Introduction to JSP advantages

JSP (Java Server Pages) is a dynamic web page technical standard proposed by Sun Microsystems and established by many companies. This article briefly introduces the advantages of JSP.

JSP (Java Server Pages) is a dynamic web page technical standard proposed by Sun Microsystems and jointly established by many companies. JSP technology uses JAVA as the scripting language. JSP web pages provide an interface for the JAVA Library Unit on the server to serve HTTP applications.

In the traditional web page HTML file (*. htm ,*. java program snippets (Scriptlet) and JSP tags are added to html to form a JSP webpage (*. jsp ). When the Web server encounters a request to access the JSP webpage, it first executes the program fragment and then returns the execution result to the customer in HTML format. Program snippets can operate databases, redirect webpages, and send emails. This is the function required to build a dynamic website. All program operations are performed on the server, and the results are only obtained after the network is uploaded to the client. The client has the lowest requirements on the client browser and can implement no Plugin, no ActiveX, and no Java Applet, no Frame.

JSP advantages:

◆ Updates to the user interface are actually performed by the Web Server, so it gives people the feeling that the updates are fast.
◆ All applications are server-based, so they can always be updated to the latest version.
◆ The client interface is not very cumbersome and is easy to deploy, maintain, and modify for various applications.

ASP advantages

ASPActive Server Pages) dynamic web Pages are a Technology launched by Microsoft to replace CGICommon Gateway Interface (CGICommon Gateway Interface) Generic Gateway interfaces. We can use ASP to combine the knowledge of HTML language, ASP commands, ActiveX components, and databases to create and run dynamic interactive Web sites on our Web servers. The advantages of ASP are summarized as follows:

1. You can use VBScript or JScript to create scripts, and use HTML to easily complete website applications. Which language does not matter for VBScript and JScript? The Web server processes the two languages and sends HTML formatting results to the user's browser.

2. Because ASP uses the Script language VBScript and JScript), you can easily write programs, which greatly saves the time for network designers to learn a new language. In addition, you do not need to compile the ASP program manually or link the program, but can directly execute it on the server side, which is undoubtedly more convenient for our compilation process.

3. Use a text editor such as NotePad to edit the design, for example, Windows notepad. We recommend that you do not use the home pages such as FontPage98 or DreamWeaver2.0 to make software modifications, because they will damage the source code. Here, we recommend that you use the CuteHTML editor carried by CuteFTP for editing and design.

4. ASP is running on the server, so we don't have to worry about whether the browser supports the programming language used by ASP. Users only need to use a browser that can execute HTML code, you can view the webpage content designed by Active Server Pages. ASP runs on the server. After the program is executed, the server only returns the execution result to the client browser, which reduces the burden on the client browser and greatly improves the interaction speed.

5. ASP is compatible with any ActiveX scripting Language. In addition to VBScript or JScript, other scripting languages provided by a third party, such as Perl and Tcl, are also used in plug-in. The script engine is a COM (Component Object Model) Component that processes scripts.

6. Hide the program code of Active Server Pages. On the client, you can only view the dynamic HTML file output by ASP. Therefore, it can avoid the plagiarism of the source program written by others and improve the security of the program.

7. Use the server script to generate the client script.

8. Object-oriented Object oriented) and extends the ActiveX Server component functions.

9. ActiveX Server Components (ActiveX Server Component) is infinitely scalable. You can use any programming language to compile the ActiveX Server Components you need.

10. The advantage of ASP is that it can use ADOActiveX Data Objects, a new Data access model of Microsoft, and a database that provides WEB page developers with easy access to the Internet, the latest WEB page database technology can be instantly updated and displayed on the Internet on the user side .) It is very convenient to access the database, making it easy to access the database.
