Subject: Slow response with HTTP 1.1?
Date: Fri, 4 Jul 2014 12:18:10 -0300
Message-ID: <CABAijKGO+TN7=Ls+xsB+DW2B-jsFNMMx4iAtF0UO3ZCDP1coMQ@mail.gmail.com> (raw)

Hi,

I'm seeing very slow (or time outs, depending on the client) for
requests made over HTTP 1.1. If I force curl to use HTTP 1.0,
everything works quickly.

The behavior is consistent over curl or when using Rainbows behind Varnish.

Any ideas?
