<PRE>thanks!

how to implement timeout callback manually? if I had receive then I would
just use timeout clause there, but with the handler I do not know...

I have doubts about validity of my question on the erlang list.  I later
realised that there is no problem receiving messages in my handler from my
upstream process, I can do it fast enough and shove everything to the
response. my real problem is to determine if the http client is reading
fast enough from the response...

&gt;<i> Loop handlers close after a while regardless of what you send, it only
</I>&gt;<i> checks what the client sends. The best way for you would be to disable that
</I>&gt;<i> timeout and handle it manually.
</I>&gt;<i>
</I>&gt;<i> As for the second question, I'm still reading the thread on
</I>&gt;<i> erlang-questions but I've seen some good ideas about timestamps so far.
