title: What is the cookie related to /_vti_bin/Discovery.asmx and why can't I set its Secure attribute?
body: <p>I have a WSS 3.0 site that uses forms authentication. In addition to my authentication cookie I get a cookie that contains data like this:</p>
  
  <pre>
  2FDiscovery=WorkspaceSiteName=aHR0cDovL3d3dy5rZWxldi5iaXo=&WorkspaceSiteUrl=
  aHR0cHM6Ly9zdGFnaW5nLWluc2lnaHQubmNqcnMuZ292&WorkspaceSiteTime=MjAwOS
  0xMi0xMFQxNDo1ODoxMQ==; path=/_vti_bin/Discovery.asmx;
  </pre>
  
  <p>This cookie does not have the Secure attribute set, even though I have requireSSL="true" in my web.config and the other cookies have the attribute.</p>
  
  <p>I do not know if this cookie originates in WSS or in forms authentication in general.</p>
  
  <p>Does anyone know what the cookie does (or what /_vti_bin/Discovery.asmx does, for that matter) and why the attribute doesn't seem to get picked up from the web.config?</p>
