Support for page/resource size

Thanks for the response!

To me, I can see value in both - would it be that much of a "cost" to pay
if both are captured and made available (as it would be handy to know both
and even be able to derive the header size)? But, personally, if I was
pushed, I would probably go with total request size. I think this would
fall inline with expectations - as I think that's what most dev tools show
and tells me the true size of the request if I care about the network
"cost".

Additionally (and I say this hoping it's not pushing my luck), I would like
to know the "over-the-wire" size vs the "actual" size (chrome dev tools
calls this "content" vs "size"). That way we can start flagging requests
that aren't compressed, see bandwidth cost of payload, etc.

Lastly (and I think this might be really pushing things), I would like to
know the status code associated with the request. This lets us flag
resources that aren't cached, have errors, etc.

Cheers
Anthony
