I am testing upgrade from Varnish 2.0 to 3.0.<div><br></div><div>In some cases, because of our advertising and analytics partners, cookies can be excessively long. This appears to be a problem in Varnish 3.0, as I get a 400 Bad Request response. When I look at varnishlog, I see a LostHeader for the Cookie header.</div>
