title: OpenId - have returnTo url requested with POST instead of GET
body: <p>How do I make it so the returnTo url after someone signs in with their openId provider is requested with POST instead of GET?</p>
  
  <p>I have a form that someone must be logged in for the POST to work.  When they press submit it redirects them to the login page and they choose their OpenID provider.  After successfully choosing and authenticating with their openID provider, it requests the page it was originally trying to request, except with GET.</p>
