Tune Varnish for pipe only operations

[Baptiste]

Hi,

I'd be keen to help you doing this with HAPRoxy.
You could play with some ACLs to make haproxy swap from a http to tcp
backend depending on your needs.
That way, you could analyse your request then let the stream go.

You can contact me offlist if you need some help.

cheers
