title: How to invalidate cache data [OutputCache] from a Controller?
body: <p>Using ASP.Net MVC 3 I have a Controller which output is being cached using attributes <code>[OutputCache]</code> </p>
  
  <pre><code>[OutputCache]
  public controllerA(){}
  </code></pre>
  
  <p>I would like to know if it is possible to invalidate the Cache Data (SERVER CACHE) for a Specific Controller or generally all the Cache data by calling another controller</p>
  
  <pre><code>public controllerB(){} // Calling this invalidates the cache
  </code></pre>
