IHttpStoredContext Interface

IIS 7.0

Defines context information for stored data.

class IHttpStoredContext

The following table lists the methods exposed by the IHttpStoredContext class.




Cleans up the stored context.




Represents context support for bi-directional WebSocket communications over a single TCP socket.

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.

You can define custom classes that implement the IHttpStoredContext interface and then create a pointer to this IHttpStoredContext class implementer by calling the new operator. You can then add and retrieve this pointer on an IHttpModuleContextContainer pointer by calling the IHttpModuleContextContainer::SetModuleContext and IHttpModuleContextContainer::GetModuleContext methods, respectively.

When the IHttpStoredContext pointer is no longer needed, the CleanupStoredContext method is called internally, where the implementer of the IHttpStoredContext interface method should usually call delete this.

Caution noteCaution:

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.
