title: Web api bearer token timeout some minutes later
body: <p>I am using asp.net web api and token based authentication. My token options is set success token expire time to 14 days later.</p>
  
  <pre><code>OAuthOptions = new OAuthAuthorizationServerOptions
  {
      TokenEndpointPath = new PathString("/Token"),
      Provider = new SimpleAuthorizationServerProvider(),
      AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
      AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
      // In production mode set AllowInsecureHttp = false
      AllowInsecureHttp = true
  };
  </code></pre>
  
  <p>And my generated token is like this.</p>
  
  <pre><code>{
    "access_token": "Mg5oQAzt9RLSUezxPYNQ7JRcJqo-uPxfOgOGHKkrJ_q56g0H8x-sjKm1mkjND0VAK3H22nwFlGNk5wfTocCb5mKMvTYwsZAv5sh0SACHdbb_9BGftMuqbFdm6wH0wXF-Sq3noF7hc2FeUUauhDfrBq5jTSou4NO3EBwjc0jj3v-yQzPGMCFxq2Q8C9uhat14rGYteYqj5mX3L5JtwHrobePL2R9lcnagNIMa44GUWQ8DVR2urP4KCrDHJf1G5pIfv94uB85I7sbf0nse7VvhYp058I8voNR9_zD1XC5-AODQJ16F484zxQokX1BWJ3gfgd86zJr2O9iKsA",

  }
  </code></pre>
