I renamed this in order to use the Object shorthand later. It makes sense now
that we're passing through a request Object to logRequest.

[Manish Jethani, 2018/05/02 13:25:14]

Acknowledged.

Maybe rename urlString to url and and url to urlObject?

[kzar, 2018/05/02 15:41:50]

I think I prefer it like it is, I find the name urlObject kind of ugly somehow.

Agreed with kzar (also in favor to avoid wrapping the line here).

     // To avoid an extra matchesAny for the common case we assumed no

     // and if necessary that our $csp filter is specific.
