I tried running apache -X under gdb, problem was system (prime client) 
timeout out. I am trying to run SPECweb, I suppose most of the people on 
the list are fimiliar with it.

Anyway I was able to read the code and figure out function called by 
(wrapper->wops->stream_opener), through layers of buffering and function 
calling. My TCP stack is returning one bytes less from the start, so 
http:// 200 is ttp:// 200.

May be it is calling pread to read the data or aio_read (something which 
is not implemented in my stack), Is there a documentation which can help 
me understand the code flow with less pain ?
