INTRODUCTION
This article describes a update that enables certain Internet Information Services (IIS) 7.0 or IIS 7.5 handlers to handle requests whose URLs do not end with a period. Specifically, these handlers are mapped to "*." request paths. Currently, a handler that is mapped to a "*." request path handles only requests whose URLs end with a period. For example, the handler handles only requests whose URLs resemble the following URL:
http://www.example.com/ExampleSite/ExampleFile.After you apply this update, handlers that are mapped to a "*." request path can handle requests whose URLs end with a period and requests whose URLs do not end with a period. For example, the handler can now handle requests that resemble the following URLs:
http://www.example.com/ExampleSite/ExampleFile
http://www.example.com/ExampleSite/ExampleFile.
After this patch is applied, ASP.NET 4 applications can handle requests for extensionless URLs. Therefore, managed HttpModules that run prior to handler execution will run. In some cases, the HttpModules can return errors for extensionless URLs. For example, an HttpModule that was written to expect only .aspx requests may now return errors when it tries to access the HttpContext.Session property.
You can turn off the extensionless URL functionality for affected ASP.NET applications by adding the following to the application's web.config file:
<system.webServer> <handlers> <remove name="ExtensionlessUrl-Integrated-4.0"/> <remove name=" ExtensionlessUrl-ISAPI-4.0_32bit "/> </handlers>
</system.webServer>

Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
If you want a handler to run a child request, you can use the EXECUTE_FLAG_IGNORE_CURRENT_INTERCEPTOR flag when you create the handler. This behavior prevents the flag from being invoked again on the child request.
The EXECUTE_FLAG_IGNORE_CURRENT_INTERCEPTOR flag is a request-execution constant that is supported in IIS 7.0 and in IIS 7.5. The flag indicates that the handler for a given request chain should be ignored. For more information about the flag, visit the following Microsoft Developer Network (MSDN) Web site:
Execution flags that control the execution behavior for a child request For more information about requirements for configuring handler mappings in IIS 7.0, visit the following Microsoft TechNet Web site:
