Features and functions of ASP language for Web site production

ASP (Abbreviation for Active Server page)

It means "Active Server Web page". ASP is an application developed by Microsoft to replace CGI scripting programs.

It can interact with databases and other programs, and is a simple and convenient programming tool. ASP's Web page files are in the format of. asp and are now used in a variety of dynamic Web sites.

ASP is a server-side scripting environment that you can use to create and run dynamic Web pages or Web applications.

Features and functions of ASP

From the software technology level, the ASP has the following characteristics:

1. No need to compile

ASP scripts are integrated into HTML and are easily generated without the need for compilation or linking to directly interpret execution.

2. Easy to generate

You can design all of the. asp pages by using a regular text editor, such as Notepad under Windows. If you consider from the work efficiency, you may choose to have the visual editing ability software.

3. Independent of the browser

The client can browse the home page designed by ASP by using a browser that interprets regular HTML code.

ASP scripts are executed on the site server side, and the client's browser does not need to support it. Therefore, if you do not download from the server to observe the entire. ASP home page, the correct page content is not visible at the browser end.

4. Object-oriented

It is easy to reference system components and ASP's built-in components in ASP scripts, as well as to extend functionality through custom ActiveX server Component (ActiveX servers components).

5. Good compatibility

Compatible with any ActiveX scripting language, in addition to being designed using VBScript and JScript languages, other scripting languages provided by third parties can be used in plug-in mode.

6. Source code does not leak out

ASP script execution on the server, upload to the user's browser is only the ASP execution results generated by the regular HTML code, so that the painstaking writing of the program code will not be stolen by others.

From an application perspective, the ASP has the following functions:

1. Process form input from the browser to the site server.

2. Access and edit server-side database tables. You can use the browser to enter, update, and delete data from the database of the site server.

3. Read and write Site server files, the realization of visitors counters, motto and other functions.

4. Provide advertising carousel, access to browser information, URL table management, such as built-in functions.

5. Cookies read and write to the client's hard disk file to record the user's data.

6. It is possible to share information among multiple home pages to develop complex business site applications.

7. Use simple scripting languages such as VBScript or JScript to combine HTML code to quickly complete your site's applications.

Script language is executed through the site server, producing or changing the scripting language that is executed on the client.

8. The ability to expand functionality allows you to make ActiveX Server component to meet your special needs by using a variety of programming languages, such as Visual Basic, Java, visual C + +, and more.

The general features of dynamic Web pages are briefly summarized as follows:

(1) Dynamic Web page based on database technology, can greatly reduce the workload of website maintenance;

(2) The use of Dynamic Web site technology can achieve more functions, such as user registration, user login, online survey, user management, order management and so on;

(3) Dynamic Web pages are not actually independent of the Web page files on the server, only when the user requests the server to return a complete Web page;

(4) "?" In Dynamic Web pages Search engine retrieval There are certain problems, search engines are not generally possible from a website database to access all the pages, or for technical considerations, search spiders do not crawl the Web site "?"

After the content, so the use of Dynamic Web site in the search engine promotion needs to do some technical processing to adapt to the requirements of search engines.

The so-called static Web page means that there is no program in the page file, only HTML code, generally with the. html or. htm suffix name of the Web page, static site content will not be changed after the completion of the production, anyone to access all the same content, if you change the content must modify the original code and then uploaded to the server.

The so-called Dynamic Web page, that is, the Web page file not only has HTML tags, but also contains program code, with the database connection, dynamic Web pages according to different time, different visitors display different content, Dynamic Web site update convenient, general in the background directly updated.
