IIS7.5 migration-HTTP error 404.0-not found-0x80070002 error analysis and resolution process

When an ASP. NET application migrates to IIS7.5, the site reports an HTTP error 404.0-not Found error. The process is as follows:
Operating environment: Framework 2.0,iis7.5,web Site set, no source code, application Chime think of Classic mode.
The URL of the error page is as follows: Http://localhost/HL2008/UI/AutoMonitor/135?autorun=true
See this URL address, the first reaction is HttpModule was rewritten, through the. NET Reflector 7.0 anti-compilation HL2008.Web.Common.dll, found Urlrewriter class, Implements the System.Web.IHttpModule interface.
Continue tracking, the core code of this class is a jump operation.

Therefore initially decided that HttpModule was not activated, through web search, to find a similar blog post (http://q.cnblogs.com/q/38592/), which mentions IIS7.5 under the httpmodules use appears: 404 To Solve, The modules configuration needs to be added to the <system.webServer> configuration section.
in the Web. config at this time, there are httpmodules and httphandlers configured under <system.web>,<system.webserver> The modules and handlers configurations are available.
The problem is still unresolved, and the application is not activated http://localhost/HL2008/UI/AutoMonitor/135 by inserting the modules component of the Log4net log into the output log in the original application? Autorun=true the request had been terminated before. The log is as follows:

The problem is defined as modules was called, but the request was not activated http://localhost/HL2008/UI/AutoMonitor/135?autorun=true.
continue, setting the application pool to Integrated mode, IIS errors are as follows:

After deployment to the production environment, the jquery framework found on the frames page failed. Continue analysis. The Discovery Framework page uses the ScriptManager control, corresponding to the generated HTML code such as:

Check the Web. config file again and add the following configuration in webserver (inspired by the code generated automatically when you create a new Web project):

The configuration in the old web. config corresponding to the preceding code is as follows:

Once again deployed to the production environment, the problem is finally resolved.
The summary is as follows:
IIS7.5 404, the HttpModule in System.Web is registered to system.webserver modules, and if the application pool is in Classic mode, module is not activated correctly. An abnormal termination occurs.
1. The module can be activated correctly only if the application pool is switched to integrated mode and the httpmodules and httphandlers configuration sections of the system.web are completely erased. (If you do not remove httpmodules and httphandlers registrations used in Classic mode, you must have the validateintegratedmodeconfiguration of the validation element  property is set to false to avoid errors. )
2. In integrated mode, the content under httphandlers under system.web in the original Classic mode needs to be migrated to system.webserver. To ensure that the httphandlers (ASP. NET Framework level) works correctly.
