How to write an asp class, the definition of an asp

ASP is an abbreviation for ActiveServerPage, which means "Active Server Web Page". ASP is an application developed by Microsoft to replace CGI scripting programs, which can interact with databases and other programs, and is a simple and convenient programming tool. The format of the asp web page file is:

ASP is now commonly used in a variety of dynamics. ASP is a server-side scripting environment that can be used to create and run dynamic web pages or web applications. ASP web pages can contain HTML markup, plain text, script commands, and COM components.

ASPs can be used to add interactive content to web pages, such as forms, or to create web applications that use HTML web pages as user interfaces. Compared to HTML, ASP web pages have the following characteristics:

1) ASP can be used to break through some functional limitations of static web pages and realize dynamic web page technology;

2) The ASP file is included in the file composed of html**, which is easy to modify and measure;

3) The ASP interpreter on the server will make an ASP program on the server side and send the result to the client browser in HTML format, so the web page generated by ASP can be browsed normally with various browsers;

4) ASP provides some built-in objects that can be used to make server-side scripting Sakura more powerful. For example, the information submitted by the user through the HTML form can be obtained from the web browser, and the information can be processed in the script, and then the information can be sent to the web browser;

5) ASPs can use server-side ActiveX setup to perform a variety of tasks, such as accessing databases, discovering emails, or accessing file systems.

6) Since the server sends the results of the ASP program execution back to the client browser in HTML format, the user will not see the original program ** written by the ASP program**, and the ASP program ** can be stolen.

ASP purchases or leases various equipment, software systems and communication lines from server vendors, network communication equipment vendors, operating system developers, database system developers, network orange security system developers, network management system developers, and communication line operators to build application system running platforms, and then leases them to different users. For users, it is "monthly rent" instead of "purchase". It can be said that ASP is gradually formed with the development of outsourcing services, software application services and communication transmission services.

The first ASPs were founded in 1998 with Breakaway Solutions, Corio and USInthro. Their business model is to rent out access to non-core enterprise applications on the Internet or other networks.

This is very different from traditional application outsourcing, which typically charges high fees for contracted IT services, and ASPs often offer options such as software rentals, services, etc., without the need to purchase software upfront.
