title: Customize HTTP header in IIS URL Rewrite module
body: <p>I was stuck by a simple outbound rule, I want to modify the HTTP <strong>Content-Type</strong> to <strong>application/atom+xml</strong>, if the URL exactly matches <a href="http://wayneye.com/Feeds/Atom" rel="noreferrer">http://wayneye.com/Feeds/Atom</a></p>
  
  <p>My rule XML:</p>
  
  <pre><code>&lt;outboundRules&gt;
  &lt;rule name="AtomFeedsIMEType" patternSyntax="ExactMatch"&gt;
      &lt;match serverVariable="RESPONSE_CONTENT_TYPE" pattern="http://{HTTP_HOST}/Feeds/Atom" /&gt;
      &lt;action type="Rewrite" value="application/atom+xml" /&gt;
