body: <p>What is the maximum expiration time we can set to an item in HttpRuntime Cache...? 
  <br/>Also what is the default expiration time..?</p>
  
  <pre><code>public static void Add(string pName, object pValue)
  {
    System.Web.HttpRuntime.Cache.Add(pName, pValue, null, DateTime.Now.AddSeconds(60), TimeSpan.Zero, System.Web.Caching.CacheItemPriority.High, null);
  }
  </code></pre>
  
  <p>In above code 4th parameter is 'absoluteExpiration'. <br/> What is the maximum value we can provide here...?<br/><br/>
  If I provide 10-05-2014, will that item available in cache for that long period...?
