title: Guacamole get the key of the share link connection
body: <p>I'm working with guacamole 0.9.14 , I want to get the share link of the connection.
   So I'm using <code>http.get</code> and <code>http.post</code> to get the key . </p>
  
  <p>At first , I got the token from </p>
  
  <pre><code>dns/guacamole/api/tokens
  </code></pre>
  
  <p>After that , I got the id connection and uuid session from <code>dns/guacamole/api/session/data/mysql/activeConnections?token=????</code></p>
  
  <p>Now I want to get the key from :</p>
  
  <pre><code>dns/guacamole/api/session/tunnels/uuidconnection/activeConnection/sharingCredentials/idsession?token=???
  </code></pre>
  
  <p>But I have this result : </p>
  
  <pre><code>{
      "message": "No such tunnel.",
      "translatableMessage": {
          "key": "No such tunnel.",
          "variables": null
      },
      "statusCode": null,
      "expected": null,
      "type": "NOT_FOUND"
  }
  </code></pre>
  
  <p>It seems that the token has changed when I did the <code>http.get</code> to get the id session and uuid connection. </p>
  
  <p>Any suggestion? </p>
