title: Can multiple bearer token supported in Authorization header
body: <p>In JAVA based application, we are receiving JWT token through <code>Authoriztion</code> HttpHeader. As I know HttpHeader can contains multiple value against one Header Key.</p>
  
  <p>So here want to know whether the <code>Authoriztion</code> http header can also contains multiple <code>bearer</code> token value in same header ? I know <code>Authorization</code> header can contains multiple token of different type like Basic, Bearer etc. </p>
  
  <p><strong>But can it also contains multiple same type of token as value ?</strong> </p>
  
  <pre><code>as example: (Whether it is valid or not)
  "Authorization" : "Bearer XXXXXX1, Bearer XXXXX2" 
  </code></pre>
  
  <p><strong>Any RFC reference will be helpful.</strong></p>
