title: How to remove HTTP specific headers in Javascript
body: <p>Is it possible to, before sending a http message, remove some specific http headers using javascript / XmlHttpRequest ?</p>
  
  <p>I'm using a proprietary browser, so there's no way to do it using browser specific solution.</p>
  
  <p>For example, I want to remove the header 'Authorization' before send the message</p>
  
  <pre><code>POST /social/rpc?oauth_version=1.0&amp; ... HTTP/1.1
  
  Accept: text/html, image/png, image/*, */*
  Accept-Language: ko
  Authorization: Basic Og==
  Host: test.myhost.com
  </code></pre>
  
  <p>Regards</p>
