title: RequestHeader not getting set on RewriteRule in htaccess
body: <p>The following RewriteRule in my htaccess file isn't getting the request header set.</p>
  
  <pre><code>Header set Access-Control-Allow-Origin "*"
  RewriteEngine On
  RewriteBase /
  
  RewriteCond %{QUERY_STRING} ^(.*)&amp;someUser=(.*)$
  RewriteRule ^(.*)SDM$ http://some.domain.com/SDM/Publish.aspx [E=SOME:%2,R,L]
  RequestHeader set Some-User: "%{SOME}e"
  </code></pre>
  
  <p>I don't think the SOME environment variable has anything to do with it because I tried a generic header value as well and it wasn't set either.  I did make sure that mod-headers is installed.  I am looking for the header in my chrome developer tools.  Is it possible that it won't show up there?</p>
