We already have a log format from the existing tool.  I'd be +1 on 
investigating that possibility for a later iteration.

Yes, already tracked.

I don't understand why that would vary significantly per URI/pageid, except 
with repeated SSL handshakes for new connections that download page components 
such as images, CSS, and JS.  We won't be able to track that easily on the 
server side, and we do have some visibility right now on the client side via 
the webpagetest.org stuff.  ...Am I missing something?

Yes.  This is a somewhat lower priority IMO, since Squid is only used for 
anonymous users.  Right now I'd just want it to validate my assumption that a 
majority of anonymous requests are cache hits in Squid.  That would be a good 
thing to validate, but we should be able to use simpler metrics.

If that assumption is not validated, or if we change our Squid scheme into 
something that is used for authenticated users, then I'll change my mind.  Even 
now, I agree that it is a nice to have.

Yeah.  We have URIs now.  Maybe it will be appropriate to look at the report 
generated from the URI perspective and then generated from the pageid 
perspective (once we have it).
