title: Maximum and default values of Access-Control-Max-Age
body: <p>I used Access-Control-Max-Age to cache options requests on a .net project. I used the code like this and want to cache it with it's largest value.</p>
  
  <pre><code>if (context.Request.HttpMethod == "OPTIONS")
  {
      response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
      response.AddHeader("Access-Control-Allow-Headers", "authorization, content-type");
      response.AddHeader("Access-Control-Allow-Credentials", "true");
      response.AddHeader("Access-Control-Max-Age", "86400");
      response.End();
  }
  </code></pre>
  
  <p>I have few questions according to Access-Control-Max-Age.</p>
  
  <ol>
  <li>What's the largest Access-Control-Max-Age value you can be used?</li>
  <li>Is maximum Access-Control-Max-Age change according to the browser?</li>
  <li>What is the default value of Access-Control-Max-Age?</li>
  </ol>
