Invoked by Microsoft Media Foundation to create an object that implements the IMFHttpDownloadRequest interface, which is used to send a single HTTP, or HTTPS request. Since multiple requests may be needed to fully download a resource, Media Foundation may invoke CreateRequest multiple times on the same IMFHttpDownloadSession instance. Media Foundation will use each IMFHttpDownloadRequest instance for only a single request.
Pointer to a string that contains the name of the target resource of the specified HTTP verb. This is generally a file name, an executable module, or a search specifier. The target resource always begins with a forward slash character and includes any query string that was included on the URL.
If set to TRUE, indicates that the request should be forwarded to the originating server rather than sending a cached version of a resource from a proxy server. When this flag is set to TRUE, a "Pragma: no-cache" header should be added to the request. When creating an HTTP/1.1 request, a "Cache-Control: no-cache" should also be added.
If set to TRUE, causes the secure variant of the protocol to be used, if applicable. For example, if the IMFHttpDownloadSession is for HTTP/HTTPS, setting fSecure to TRUE will cause the request to use HTTPS. Otherwise, the unsecure variant of the protocol (in this example, HTTP) is used.
Pointer to a string that contains the HTTP verb to use in the request. If this parameter is NULL, the function uses GET as the HTTP verb.
Pointer to a string that specifies the URL of the document from which the URL in the request szObjectName was obtained. If this parameter is set to NULL, no referring document is specified.
Upon successful return of the method, this parameter is set to an IMFHttpDownloadRequest interface.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
