    <p>Thanks for you answer.<br>
      I was thinking about that also, but I could not find anything that
      pointed in that direction.<br>
      But should I hit that limit also with the info.html file then or
      could it be the size of the page.<br>
      The info.html is off cource way smaller than the whole php.info

              <p>Hello all, First sorry for the long email.<br>
                I have a strange issue with varnish. At least I think it
                is strange.</p>
              <p>We start some tests with varnish, but we have an issue.<br>
                <br>
                I am running varnish 4.1.6 on FreeBSD 11.1-prerelease.
                Where varnish listen on port 82 and apache on 80, This
                is just for the tests.<br>
                We use the following start options.<br>
                <br>
                # Varnish<br>
                varnishd_enable="YES"<br>
                varnishd_listen="<a href="http://192.168.2.247:82"
                  target="_blank" moz-do-not-send="true">192.168.2.<wbr>247:82</a>"<br>
                varnishd_pidfile="/var/run/<wbr>varnishd.pid"<br>
                varnishd_storage="default=<wbr>malloc,2024M"<br>
                varnishd_config="/usr/local/<wbr>etc/varnish/default.vcl"<br>
                varnishd_hash="critbit"<br>
                varnishd_admin=":6082"<br>
                varnishncsa_enable="YES"<br>
                <br>
                We did a test with a static page and that went fine.
                First we see it is not cached, second attempt is cached.<br>
