title: Lifetime and multiple use of an AntiForgeryToken?
body: <p>I'm trying to implement antiforgerytokens to an angular application's ajax requests.</p>
  
  <p>Is there a lifetime attached with the antiforgerytoken? If I have the app open for a long while in a web browser whithout touching it, say for a month. Will the ajax requests fail due to a stale token?</p>
  
  <p>Can the token be reused for multiple calls? Can I keep one token somewhere in the page and retrieve it for all ajax calls?</p>
