Make spec-compliant about cors

[jonathanong]

@dougwilson we may want to think about how to make a pillarjs module. i wouldn't use it as middleware as my CORS requests typically are very route specific.

OK, I will read the spec deeply and send a pull request to make thing right.

@jonathanong I had thought about it. There is a module https://www.npmjs.com/package/cors which is good and compliant that I use (though the source is hard to follow since it nests so deep, but eh). I actually believe I asked once if the author was interested in turning it over to expressjs, but it was declined and I left it at that :)

@troygoode let us know if you ever get tired of fielding that module alone ;)

[troygoode]

@dougwilson actually I don't think you ever asked (or if you did, I somehow missed that message). I'll definitely think on it

[dougwilson]

@troygoode it's hard for me to remember ;) I looked really hard and apparently I confused that with the corser module, haha (it's the corser module I had asked about prior). My offer for expressjs status is still there for you, though, so consider this my first offer to you, haha.

P.S. zero pressure, so feel free to continue as you always have :)!

Hey @troygoode just wanted to ping in case you've changed your mind at all ;)

[troygoode]

hey @dougwilson - I'll shoot you an email. I'm interested in transferring it over to the expressjs group
