Can we pull the initialURL off ResourceResponse, since it has the full redirect
chain? Less data duplication that way.

[arthursonzogni, 2016/09/09 12:45:33]

That is certainly one reason why I liked having the redirect responses inside
the request.

Currently, I use initialURL() inside PerformanceResourceTiming's constructor. I
certainly can add some method/arguments to PerformanceResourceTiming in order to
pass the initial url from the resource response.

My main concern is that I have some futur CLs that fix tests by simply use
request.initialURL() instead of request.url(). And there is no ResourceResponse
in the neighborhood.

I think I will remove initialURL() from ResourceRequest for the moment.
