Igor's Passthru APP question

I am using Igor's Passthru APP. The only change is that I create and
store my own HTTP response in buffer inside CTestSink class using
IHttpNegotiate and IInternetProtocolSink methods. In order to send the
response to browser I need to call IInternetProtocol::Read and pass
pointer to the buffer. However CTestSink does not implement
IInternetProtocol. I noticed that CTestAPP implements
IInternetProtocol. I was thinking that if I can pass pointer to buffer
from CTestSink to CTestAPP::Read it would solve the problem. How can it
be done? Is there a better way to communicate between these two
objects?

Thanks for help.

Max.
