title: Set / Get JSessionID - Proxy blocks set-cookies attribute
body: <p>I got a problem using the Angular-Proxy to get/set the JSessionID for a @SessionBean. (What is usually handled by the Browser?)
  I´m trying to send the Request from localhost:4200 to localhost:8080. To overcome the CORS-Problem, I use a Proxy (proxy.conf.json) like that: </p>
  
  <pre><code>{
    "/test/": {
      "target": "http://localhost:8080/",
      "pathRewrite": {
        "^/test/": ""
      },
      "secure": false,
      "logLevel": "debug",
      "changeOrigin": true
    }
  }
  </code></pre>
  
  <p>Now I was trying to use the HttpInterceptor to intercept the request and the response to read the set-cookie header and set it in the following request. 
  The problem here is, that (at least i think so) the proxy kind of filters the set-cookie header so the intercepted response is without the set-cookie attribute with the jsessionid. </p>

  When I try this with Postman, everything works fine :/ 
  Any Idea to change the proxy setting to allow the headers, so I can set the JSessionId in the Interceptor 
  OR 
  Any other idea ?</p>
