title: Ruby on Rails Invalid Authenticity Token when using IE
body: <p>well for some strange reason IE gives me and InvalidAuthenticityToken error almost every time a POST query is used. Seems to be that IE does not like the "/" and "=" characters sometimes found in authenticity_token. So I wondered if anyone has actually found a solution to this?</p>
  
  <p>More strange is that no other browser seems to behave that way.</p>
  
  <p>Thanks in advance.</p>
