Aha. Thanks this makes more sense. 7ms with a response versus 20 seconds
with nothing returned.

Although for better debug you should get the squid-3 to leave upstream
server IP address in the log. It could be some problem of which IP is
being connected to by Squid.

With 3.2 at "debugs_options 11,2" you get a cache.log HTTP trace of what
is going between Squid and optimizely and client. I suspect optimizely
is not responding when a request is delivered to them - but you need to
track that down.
