Um, I don't follow. You *do* want Varnish to cache the file? If so, then
you don't want to return pass on the URL. In that case, you need a
larger value for send_timeout (assuming my guess is right that
send_timeout aborted your connection).

There's always a send_timeout, 10 minutes by default, but you can
increase it. If you have return(pass) on the URL, then the timeout won't
interfere with the transmission, but then Varnish won't be caching the
object.

If you want Varnish to cache and transmit the object, you need to remove
return(pass), but set a higher value for send_timeout. Try starting
varnishd with -p send_timeout=1200 -- in your first mail, it looked like
53% had been transmitted in 10 minutes. so the timeout would have to be
about twice as long.


Best,
Geoff
