IIS 6.0 and previous versions allowed the development of. NET application components via the ASP. ASP. Integrated with IIS via an ISAPI extension, and exposed its own application and request processing model. This effectively exposed the separate server pipelines, one for native ISAPI filters and extension components, and another For managed application components. ASP would execute entirely inside the ASP. NET ISAPI extension bubble and only for requests mapped to ASP. NET in the IIS script map configuration.

IIS 7.0 and above integrates the ASP. NET runtime with the core Web server, providing a unified request processing pipeline That's exposed to both native and managed components known as modules. The many benefits of integration include:

• Allowing services provided by both native and managed modules to apply to all requests, regardless of handler. For example, managed Forms authentication can is used for all content, including ASP pages, CGIs, and static files.
• Empowering ASP to provide functionality that is previously unavailable to them due to their placement in T The He server pipeline. For example, a managed module providing request rewriting functionality can rewrite the request prior to any server proces Sing, including authentication.
• Implement, configure, monitor and support server features such as single module and handler mapping conf Iguration, single custom errors configuration, single URL authorization configuration.

English part of the content link here. This is not the difference between Classic mode and integrated mode, but rather the difference between different versions of IIS, IIS7.0 has made some changes to internal processing methods (such as request requests, especially authentication), or it can be understood to solve the deficiencies or optimizations of previous versions of the design, but also to ensure full compatibility with the previous IIS, so to a compatible legacy IIS took a selection name, called " Classic mode. The improved (IIS 7.0) selection name is called "Integrated mode" Integrated. Perhaps more understanding will be more profound.
