When using the IIS server, let's take a look at the knowledge of the IIS server. IIS Server 5. the isolation of the two pipelines under the IIS Server 6.0 and the IIS server brings at least the following limitations and limitations, such as repeated execution of the same operation: IIS server and ASP.. NET, such as identity authentication.

Dynamic files and static files are processed differently: because they are only Based on ASP. NET Dynamic files such. aspx ,. asmx ,. (svc. NET isapiinto the asp.netpipeline, and some static files such as. html ,. xml ,. if the request is directly responded by the IIS server, ASP. some functions in the NET pipeline will not be used for these static file-based requests. For example, we want to use Forms authentication for image file-based requests.

Difficult to expand IIS servers: the extension of IIS servers is basically reflected in custom isapis, but this is not an easy task for most people. Because ISAPI is a Win32-based unmanaged API, it is not an application-oriented programming interface.

What we usually want is to extend IIS by hosting code like defining ASP. NET's HttpModule and HttpHandler. For IIS on the Windows platform, ASP. NET is undoubtedly a first-class citizen. It should not be the relationship between them, but "you have me, I have you.

Therefore, the IIS server 7.0 integrates the two. For IIS Server 7.0 in integration mode, we get the following benefits.

Allows us to define IIS modules in two ways: Native Code) and Managed Code (Managed Code). These IIS modules are registered into IIS to form a common request processing pipeline. The pipeline composed of these IIS modules can process all requests, regardless of the resource type of the request.

For example, the IIS server can apply the Forms authentication provided by FormsAuthenticationModule to requests based on. aspx, CGI, and static files. Apply some powerful functions provided by ASP. NET to areas that are hard to match. For example, place the URL rewriting function of ASP. NET before authentication. Implement, configure, detect, and support some server features in the same way), such as Module, Handler ing, and Custom Error Configuration.
