[squid-users] youtube videos take 60 seconds to start

[mabraFoo]

I started working with squid a few months back.  First of all, if you are a
squid developer.  THANK YOU for this awesome software.

I am using ssl_bump in transparent mode.  When I use my ipad with safari
and go to youtube there is a 60+ second delay before the video starts.  My
guess is that squid is downloading the entire video and is not sending
until the entire download is complete.  Does anyone know if there is
something I could change in my config to get the video to start without
that delay?

If you see anything off in my config, please explain.
