Weren't you going to make ResourceRequest be null instead of having a boolean flag?

Yes...I think that version of the patch must have gotten lost on my other computer. Will fix now.

I think you should either call this willSendRequest or willSendRequestAsync. It should also take a ResourceRequest&&.

I wanted to call it willSendRequestAsync, but due to C++ overloading rules and the fact that there's already a function called that that's protected, with a different signature, it didn't let me.

I'll change the signature though.
