Remarks
Many IIS 7 classes maintain a private IDispensedHttpModuleContextContainer pointer as a member variable. These classes implement various interfaces, including IHttpApplication, IHttpConnection, IHttpContext, IHttpFileInfo, IHttpSite, IHttpUrlInfo, and IMetadataInfo.
Each of these interfaces defines a GetModuleContextContainer method, which accepts no arguments and returns an IHttpModuleContextContainer pointer. When the various GetModuleContextContainer methods are called, most of these implementers return the private data as an upcast IHttpModuleContextContainer. This allows the interface implementers to expose custom containers while maintaining the lifetime of those containers.
Caution
While it may be a safe operation to downcast an IHttpModuleContextContainer to an IDispensedHttpModuleContextContainer by using the dynamic_cast operator, you should avoid performing this cast. The IDispensedHttpModuleContextContainer interface adds only one method, ReleaseContainer, to its base interface, and this method should be called only internally.
