IHttpContext::GetConnection Method

IIS 7.0
 

Retrieves the connection container for the current context.

virtual IHttpConnection* GetConnection(
   VOID
) = 0;

This method takes no parameters.

A pointer to an IHttpConnection interface.

The GetConnection method retrieves a pointer to an IHttpConnection interface that can be used to retrieve information about the current connection. For example, the IHttpConnection::IsConnected method returns a Boolean value that indicates whether a Web client is still connected to the current request.

System_CAPS_noteNote

IHttpContext owns the lifetime of this object. Therefore, you do not free this pointer when you write your application.

Example

The following code example demonstrates how to use the GetConnection method to create an HTTP module that retrieves a pointer to an IHttpConnection interface. The example then calls the IHttpConnection::IsConnected method to determine whether the Web client that initiated the current request is still connected. If the client is still connected, the HTTP module will return a status message to the Web client. If the client is not connected, the module will return RQ_NOTIFICATION_FINISH_REQUEST to end additional processing.

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
