I am attempting to provide a response to the HTTP OPTIONS method with an Access-Control-Allow-Origin header copying the contents of the Origin header in the request.
This is apparently not working, for reasons I can't figure out.
tl;dr: response from OPTIONS says:
Access-Control-Allow-Origin: http://10.0.0.105:9294
subsequent GET has:
Origin:http://10.0.0.105:9294
Chrome says:
Origin http://10.0.0.105:9294 is not allowed by Access-Control-Allow-Origin
WTF not?
More detail...
By looking in Chrome's developer tools window, the request headers are:
OPTIONS /user/kris HTTP/1.1
Host: 10.0.0.104:8080
Connection: keep-alive
Access-Control-Request-Method: GET
Origin: http://10.0.0.105:9294
User-Agent: Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.75 Safari/537.1
Access-Control-Request-Headers: origin, x-requested-with, content-type, accept
Accept: */*
Referer: http://10.0.0.105:9294/
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-GB,en-US;q=0.8,en;q=0.6
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3
The response headers are:
HTTP/1.0 200 OK
Date: Mon, 13 Aug 2012 11:23:45 GMT
Server: WSGIServer/0.1 Python/2.7.3
Content-Length: 0
Access-Control-Allow-Methods: GET, PUT, POST, DELETE, HEAD, OPTIONS
Access-Control-Max-Age: 10
Access-Control-Allow-Origin: http://10.0.0.105:9294
Access-Control-Allow-Headers: X-Requested-With, Authorization, X-Huzu-User, Content-Type, Accept
Content-Type: text/html; charset=UTF-8
After jQuery sends its OPTIONS request and gets the above response, 2 odd things happen. The OPTIONS response (which is a 200) shows up in the developer console as an error:
OPTIONS http://10.0.0.104:8080/user/kris 200 (OK)
After which a GET request is rejected. Error in the console:
XMLHttpRequest cannot load http://10.0.0.104:8080/user/kris. Origin http://10.0.0.105:9294 is not allowed by Access-Control-Allow-Origin.
I can't see why not. What am I doing wrong?
