title: Use wildcards when searching in HttpContext.Cache
body: <p>Is there a way to use wildcards or a regex to search and remove items from <code>HttpContext.Cache</code>?</p>
  
  <p>I can have in my cache "item_1", "item_2",...,"item_n" and I want to remove from cache all values that are related to keys with the pattern "item_*". How to achieve that without checking if the item exists and then remove it?</p>
  
  <p>Ex:</p>
  
  <p>instead of:</p>
  
  <pre><code>HttpContext.Current.Cache.Remove("item_1")
  HttpContext.Current.Cache.Remove("item_2")
  HttpContext.Current.Cache.Remove("item_3")
  </code></pre>
  
  <p>I want something like:</p>
  
  <pre><code>HttpContext.Current.Cache.Remove("item_*")
  </code></pre>
