Duplicated Content-Length headers on pass

[Tollef Fog Heen]

Hi all,

it seems like a small, but pesky bug snuck its way into 2.1.4, in which
you might see duplicated Content-Length headers when using pass.

As a workaround for this, I believe doing

  sub vcl_fetch {
    if (req.request != "HEAD") {
      unset beresp.http.content-length;
    }
  }

should work, or you can use the patch from
http://www.varnish-cache.org/trac/changeset/5461

This will also hit the 2.1 SVN branch in a few minutes.

Feedback on whether this bug poses a real-world problem for people or
not would be most welcome.

Regards,
