LastResponseInfo only works for HTTP transport.
Before sending a file to a HTTP server, a message is sent to the server
in a form of a request, and immediately thereafter Framework EDI (FREDI)
receives a message in response to that request, if any.
That response message can be retrieved by interrogating this property.
By default, if the receive or send function succeeds FREDI
does not wait for the response message.
Technical Note: This property should not be confused as
error text returned by the API InternetGetLastResponseInfo() of Wininet.dll.
When extended error information is returned as a result of an error in
any of the Win32 Internet function calls, the description of the error is
displayed when the error or warning is generated.
This error description is also saved in the ediWarning object that is
also generated as a result. In
contrast, the text returned by LastResponseInfo is text returned by the server
when the Wininet API HttpSendRequest (or HttpSendRequestEx) and HttpQueryInfo
are called.
