Hi Mike, I'm not sure even setting the headers would work (although I haven't tried this in a while). My recollection is that part of CORS is that an OPTIONS request is sent to Shindig's rpc endpoint as part of the "pre-flight" step. The rpc servlet doesn't support OPTIONS and will return a 405. This is something we could and probably should look at fixing in Shindig but no one has taken the time to do so so far as I know. Again, it's been a while since I've investigated this so things may have changed.
The alternative, and what I've personally done, is have a proxy on the container page's domain that can proxy the /rpc calls to Shindig. That works just fine. You simply setup your API_HOST and API_PATH to utilize the proxy url. Hope that helps. -Stanton From: Michael Matthews <matth...@oclc.org> To: <dev@shindig.apache.org>, Stanton Sievers/Westford/IBM@Lotus, Cc: Douglas Davies <davi...@oclc.org> Date: 03/22/2012 11:17 Subject: Re: Shindig running on different domain than container REVISITED First of all, thanks for the quick response to this. I've modified our UI to pass the API_HOST and API_PATH as mentioned below. I know see an HTTP OPTIONS request failing.

Origin http://localhost:8080 <http://localhost/> is not allowed by Access-Control-Allow-Origin. The OPTIONS request has the following headers set: Access-Control-Request-Method: POST Origin: http://localhost:8080 Access-Control-Request-Headers: Origin, Content-Type I found the post http://www.mail-archive.com/dev@shindig.apache.org/msg03230.html which suggests additional configuration is required to set this in the PHP version of Shindig. In the java version of shindig, is there additional configuration required to set a Access-Control-Allow-Origin header on the response to allow the cross-site request?
