ASP. NET is a unified web development platform that allows developers to create enterprise-level Web applications.ProgramRequired services. Although ASP. NET syntax is basically compatible with ASP, it also provides a new programming model and infrastructure to improve application security, scalability, and stability. By gradually adding the ASP. NET function to the existing ASP application, we can freely increase it. ASP. net is a compiled, based on.. NET environment. We can use any.. Net compatible language (including Microsoft Visual Basic. net, Microsoft Visual C # And Microsoft JScript.. net) to create applications. In addition, the entire Microsoft. NET Framework can be used in any ASP. NET application. Developers can easily benefit from these technologies, including the managed public Language Runtime Library environment, type security, inheritance, and so on.
ASP. NET has the following advantages:
1) manageability: ASP. NET uses a text-based and hierarchical configuration system to simplify the application of settings to server environments and Web applications. Because the configuration information is stored in plain text, you can apply new settings without the help of local management tools. Any changes to the configuration file can be automatically detected and applied to applications.
2) Security: ASP. NET provides default authorization and authentication solutions for Web applications. Developers can easily add, delete, or replace these solutions based on application needs.
3) easy deployment: by simply copying necessary files to the server, ASP. NET applications can be deployed on the server. You do not need to restart the server, or even deploy or replace the compiled Code You do not need to restart.
4) Enhanced Performance: ASP. NET is the compiled code running on the server. Unlike the traditional Active Server Pages (ASP), ASP. NET can use early binding, real-time (JIT) compilation, local optimization, and new cache services to improve performance.
5) Flexible output cache: According to application needs, ASP. NET can cache page data, part of the page, or the whole page. Cached items can depend on cached files or other items, or can be refreshed Based on expiration policies.
6) Internationalization: ASP. NET uses Unicode internally to indicate request and response data. You can configure internationalization settings for each computer, directory, and page.
7) mobile device support: ASP. NET supports any browsers on any device. Developers use the same programming technology as traditional desktop browsers to handle new mobile devices.
8) scalability and availability: ASP. NET is designed to be scalable and has special proprietary functions to improve the performance of the cluster and multi-processor environment. In addition, Internet Information Service (IIS) and ASP. net, so that when a process encounters an exception, you can create a new process at this location so that the application can continue to process the request.
9) tracking and debugging: ASP. NET provides the tracking service, which can be enabled during application-level and page-level debugging. You can choose to view the page information, or use the application-level tracking and viewing tool to view information. When development and applications are in the production status, ASP. NET supports local and remote debugging using the. NET Framework debugging tool. When an application is in production status, the trace statement can be left in the product code without affecting performance.
10) integration with. NET Framework: Because ASP. NET is part of the. NET Framework, the functions and flexibility of the entire platform are available to Web applications. You can also smoothly access the. Net class library and message and data access solutions from the web. ASP. NET is independent of other languages, so developers can select the language most suitable for applications. In addition, the interoperability of Public Language Runtime libraries also saves existing investment in com-based development.
11) compatibility with existing ASP applications: ASP and ASP.. Net can run concurrently on the IIS web server without conflict with each other. net causes the existing ASP application to crash. ASP. NET only processes files with. aspx file extensions. Files with. asp file extensions are processed by the ASP engine. However, it should be noted that the session Status and application status are not shared between ASP and ASP. NET pages.
