Probably deserves its own context and client should be copied from the actual fetch. 107235 1 annevk 2014-06-04 07:22:12 +0000 Mike, this might be of interest to you. What context to use for CORS preflight. 107236 2 mkwst 2014-06-04 07:31:13 +0000 Why would you suggest a new context? If I'm requesting an image with the crossorigin flag, I think I'd expect the CORS preflight to be blocked by `img-src 'none'`. Without thinking about it too hard, I'd suggest that the context be copied from the fetch as well as the client. 107237 3 annevk 2014-06-04 07:38:01 +0000 Fair I guess. I was thinking new context since some parameters (such as credentials) are different, but what you say makes much more sense. 107268 4 annevk 2014-06-04 12:38:50 +0000 https://github.com/whatwg/fetch/commit/54b2bfedc0079f1af793a957e9e84584ec9f7a03
