Implementing CORS support in ASP.NET Web APIs

Hi 
I have downloaded your code and I have hosted on IIS server and call it from different browsers (Cross browser), and every time it is giving an error not calling action of controller. Is dere any thing wrong with code sample.

I can see now there is a released version of Web API.

Do we need to follow the same process to have CORS enabled in the released version of WebAPI?

Is there any link to help for the latest version?

Working on IE 9 w/cookies:
  Origin: app.foo.com
  WebApi: app.foo.com:8080

Not working on FF 19.0.2 with cookies:
  Origin: app.foo.com
  WebApi: app.foo.com:8080

Not Working on FF 19.0.2 with cookies:
  Origin: app.foo.com
  WebApi: svc.foo.com

Not Working on IE 9 at all, no request made:
  Origin: app.foo.com
  WebApi: svc.foo.com

Sorry for the multiple posts. Any help would be oh so appreciated. I am using jQuery to make the requests - all GET requests so far.

Thanks!!!

I was wrong and right in my earlier question. I can get this to work from IE (cookies and all) if the origin & webapi urls are the same but differ by port. E.g. origin (app.foo.com) webapi (api.foo.com or api.bar.com).

Any ideas how or if this can work?

First - great post!

I got this to work with IE & FF but FF won't send cookies even though I return Access-Control-Allow-Credentials: true.

Any thoughts about if this can work with FF (and eventually Safari & Chrome)?

Thanks!

Not sure why you defined constants for Origin, AccessControlRequestMethod, etc... and then didn't include them in your code example.  Makes it pretty confusing for anyone trying to work from the code sample without downloading your whole project.

Hi ,
I already download your uploaded project and run it but it did'nt work and it return just error !! 
what is the problem bro ?

+1 this question.. because it is awesome

Hi,
I looked at the code sample for CORS support. Its just came to my mind.Do you think there will be any issue with HTTPS ?

Thanks for your pointers.

Yes, this should work for HTTPS as well.
