Description David Moore 2020-02-26 13:26:32 PST 
_WKResourceLoadDelegate does not currently provide a method for signing URL requests for sub-resource loads. A willSendRequest SPI should be added to _WKResourceLoadDelegate to provide an opportunity to attach dynamic headers (i.e., cryptographic signatures).

Sharing the existing _WKResourceLoadDelegate infrastructure, -[WKResourceLoadDelegate webView:resourceLoad:willSendRequest:] will return an NSURLRequest synchronously via the delegate implementation.

Builds are failing due to a last minute formatting change to pass the style requirements.

_WKResourceLoadDelegate callbacks are intentionally informative only.  Waiting for this roundtrip will considerably hurt performance when a resource load delegate is set.
