title: How to remove duplicate Cache-Control property from response headers
body: <p>I need to remove duplicate entries of one property of response headers
  "Cache-Control"</p>
  
  <p>I actually want Cache-Control to come as private hence I went to IIS settings and went to the desired folder and added a customer http response header value as </p>
  
  <p>"Cache-Control" with value as "private"</p>
  
  <p>Now I am viewing as "no-cache,private" as its value when I see a request from my fiddler properties.</p>
  
  <p>I need to do it from IIS level.</p>
  
  <p>Any inputs?</p>
