  Facebook Authentication and strange redirect behaviour

  Oct 21, 2011 01:04 AM|LINK

  Hi,

  I'm currently testing an OAuth implementation of facebook connect using http://facebooksdk.codeplex.com.

  I've got a FacebookController with 2 simple actions called LogOn and CallBack.

  Everything works fine and the user is logged correctly into my system.

  The problem is when the CallBack action is called, something strange happens that makes a simple

  return Redirect(loggedUrl);

  redirecting to the correct logged url but ending with the following characters: #_=_

  It appears that the Facebook server sends the information to my webserver using the following HTTP header:

  HTTP/1.1 302 Found
  Cache-Control: private, no-cache, no-store, must-revalidate
  Expires: Sat, 01 Jan 2000 00:00:00 GMT
  Location: http://mywebsite.com/Facebook/CallBack/?state=1&code=AQCXexr10uxANSBOu9JqrBDxqPkWbsyxM1S9ltuY9XwCXW7eGsOII329SthClx

                usuhSKacmsTcV1LAOW4uJ3K4#_=_
  P3P: CP="Facebook does not have a P3P policy. Learn why here: http://fb.me/p3p"
  Pragma: no-cache
  Set-Cookie: locale=en_US; expires=Fri, 28-Oct-2011 00:09:38 GMT; path=/; domain=.facebook.com
  Content-Type: text/html; charset=utf-8
  X-FB-Server: 10.43.103.61
  X-Cnection: close

  Content-Length: 0

  As you can see we can find the #_=_ characters at the end of the Location value.

  It's like the Redirect was taking into account the #_=_ characters by adding them automatically to the loggedUrl.

  Any idea would be really appreciated.

  Thanks in advance for any answer.

  Regards,

  LB
