title: equivalent of http-proxy-option custom header on openvpn
body: <p>i want to know if exist the equivalent of these openvpn options on nginx(or squid/privoxy):</p>
  
  <pre><code>http-proxy my.VPS.IP.server 8080
  http-proxy-option CUSTOM-HEADER X-Online-Host custom.website
  http-proxy-option CUSTOM-HEADER Host custom.website
  </code></pre>
  
  <p>i can't find anything clear for me.</p>
  
  <p>What i want:</p>
  
  <p>(instead of set a custom header in openvpn i want to set it directly on vps on nginx or squid so i'll could have it also using other vpn protocol.)</p>
  
  <p>example
  :</p>
  
  <ul>
  <li><p>i set a custom header blabla.com</p></li>
  <li><p>then i connect to my vpn and  i make a request to g00gle.com</p></li>
  <li><p>my ISP have to know that i'm surfing on blabla.com but instead i have access to g00gle.com</p></li>
  </ul>
  
  <p>That happens with the http-proxy-option that i write at the top of this post.</p>
  
  <p>It's possible to do it  or OpenVPN is the only one to make it possible?</p>
