Is http server and http client possbile?

Hi,

I have a HTTP server running and the cgi is working fine.
I added http client and now the cgi is taking about 10 seconds to respond.

I think the cgi keeps the response to any HTTP REQUEST until the http client task is complete.  My question is, how do I get the cgi to send the response(infomation in its buffer) immediately?  I added a yield statement hoping to give control back to the http_handler but that didn't work.  I am not sure why my cgi won't send response right-away. Do you guys have any advice?


while (1) {			
  
  costate {
      http_handler();
  }			
			
  costate {
    yield;  //GIVE CONTROL BACK TO http_handler(), cgi 
			
    retval = httpc_init (&hsock, sock);
    if (retval)
    {
       printf ("error %d calling httpc_init()\n", retval);
    }
			
    retval = httpc_post( &hsock, DEST, 80, FILENAME, NULL, PostUpdate_Msg);
    if(retval){
	printf ("error %d calling httpc_post()\n", retval);
    }
			

    //Skip Header reading and only read body
    httpc_skip_headers(&hsock);   //skip header reading
    do
    {
	 retval = httpc_read_body( &hsock, PostResponse_msg, 128);
    } while(hsock.state == HTTPC_STATE_BODY);

    httpc_close(&hsock);
  }
}
