title: Response.Headers and IIS6
body: <p>So I'm trying to iterate over Response.Headers for a custom caching job, but I'm getting the following error when I touch the thing:</p>
  
  <pre><code>This operation requires IIS integrated pipeline mode
  </code></pre>
  
  <p>It this possible to do in IIS6? Is there a workaround?</p>
  
  <pre><code>var allHeaders = HttpContext.Current.Response.Headers;  
  // error thrown as soon as it's accessed
  </code></pre>
