Switch/Continue approach giving different thread id's   

Hello Igor,

1.I am calling Switch() method from OnResponse() .
2.Then call goes to Continue() method .
3.In this Continue() method I am getting the thread ID using the
function GetCurrentThreadId().
4. The thread Id's (for a single html page ) that I get are not all
same. i.e for a single page I have multiple thread id's

By calling switch the continue() should be called on the main thread,
right !!
Then how is it that I am getting different thread id's

I want to identify what all request/response pair belongs to a page.
(Even when multiple IE windows are open) . So I was trying to identify
it by using the thread ID of the main thread.

Is there any other way to achieve ??

Your response is much awaited,
Thanks & Regards
Hitesh

I've tested it, and I get the same thread ID every time.

Be aware that the real protocol itself may call Switch, and receive 
Continue. It may not pass PD_FORCE_SWITCH flag, and Continue call 
resulting from such a Switch call may not arrive on the main thread. You 
need to distinguish between your Continue calls arriving in response to 
your calling Switch, and all other ones. Probably the easiest way is to 
put some distinctive value into PROTOCOLDATA::dwState, and check for it 
in Continue. If Continue comes with the same value, it's yours; if not, 
you need to forward it on to the real protocol but otherwise ignore it.

Hello Igor,

Thank you so much ---- You have given such a brilliant solution for
identifying who is calling the Continue() method.

Thanks again for your guidance.
