please, try to send fewer messages, with a bit more useful information.
let's try this:
curl -I http://localhost/Naserfeiz.mp4 -o /dev/null -H "track: yes"
curl -v -k -X PURGE http://localhost/Naserfeiz.mp4 -o /dev/null -H "track:
yes"
curl -I http://localhost/Naserfeiz.mp4 -o /dev/null -H "track: yes"
varnishlog -d -q "ReqHeader:track" -g request
