hi,
i am developing proxy server application using libwww.
My application stands in between Browser 

and Remote server. My application receives request
from the browser and passes it to the remote 

server and receives data from remore server and passes
to client (i.e.browser) 
The following function i have written for GET request.
In GET request, http request is broken as 

several requests.For the first part request is going
to remote server and getting response 

properly. In second request it is going infinite loop.

i tried to debug the application, this returning from
the function AsyncWindowProc() of 

HTEvtList.c from the following code
 /* timeout stuff */
if (uMsg == WM_TIMER) 
{	HTTimer_dispatch((HTTimer *)wParam);
	return (0);
}

unable to understand why this function is getting
returned.

anybody helps will be greatly appreciated
