Hello,Using Varnish 4, I have a set of backends that're responding with a
valid Content-Length header and no Transfer-Encoding header. On the first hit
from a client, rather than responding to the client with those headers, Varnish
is dropping the Content-Length header and adding Transfer-Encoding: chunked to
the response. This is especially happening for fonts. The same data when
fetched from apache and nginx works like a charm and continue to be problematic
when used varnish in front. I've tried a number of semi-obvious things
like below but all in vain:beresp.do_stream = trueberesp.do_gzip = falseunset
