client keepalive on high trafic site

[Václav Bílek]

Hello

We have a problem with varnish using keepalive for clients, when
established connections goes above 8K varnish slows down which means the
site stops reponding.

Unfortunately we cant use
	set   resp.http.Connection="close";
because IE6 has problem with that ( after loading page source there is a
lag(few seconds) before downloading page elements)

is there any way how to disable keepalive just for certain clients (IE6);

How hard would it be to implement global keepalive off in varnish?


thanks for you time
