  • That the facebook takes care of. If the client clicks, allow, facebook will redirect the user to the RedirectURL that u have given to facebook with an auth Token string/response. You just have to do a GetResponse() and check if it is authenticated. Try the demo project in http://www.codeproject.com/KB/web-security/OpenIdFormsAuth.aspx. With this u can achieve the single sign on with any site that expose a open id endpoint. – Raghav May 11 '11 at 09:40

  • Can you give me an example of RedirectURL with the auth Token string/response. And please can you tell me how to do that GetResponse? PLEASE?i am working in c#. – linuxx May 11 '11 at 09:45
  • I did a webpage recently like the one u mentioned. There is a free-source library called DotNetOpenAuth.dll. The code project link i have attached uses it for google/twitter etc. You can download the demo proj and run it(It will not work if u r behind proxy-firewall). The second link is for facebook. Both has the GetResponse methods' sample code. All you need to do is add the DotNetOpenAut.dll as reference and copy the GetResponse() method. Modify the web.config as per your website name and convenience. – Raghav May 11 '11 at 09:50
