Unable to read http header values in javascript

Question

While trying HTTP headers which had i set on server unable to access back on java script.below is my code.Kindly some help me to resolve this.

Jersey :

@Path("/redirect")
public class RedirectDemo {

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response getRedirect(@Context ServletContext context,UserTO user) {
    UriBuilder builder = UriBuilder.fromPath(context.getContextPath());
    System.out.println("User name is:"+user.getUserName());
    System.out.println("Password is:"+user.getPassword());
    builder.path("/main.html");
    return Response
            .status(Response.Status.SEE_OTHER)
            .header(HttpHeaders.AUTHORIZATION,"Response authorize")
            .header("Access-Control-Allow-Origin", "*")
            .header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT")
            .header("Access-Control-Expose-Headers",HttpHeaders.AUTHORIZATION)
            .header(HttpHeaders.LOCATION, builder.build())
            .build();

    </form>
</div>
<script>
    function doLogin() {
        var userName = window.btoa(document.getElementById('emailId').value);
        var password = window.btoa(document.getElementById('password').value);
        var formData = JSON.stringify({userName:userName,password:password});
        var xhr = new XMLHttpRequest();  
        xhr.open("POST", "/JerseyPageRedirection/redirect/redirect");  
        xhr.setRequestHeader("Content-type", "application/json");
        xhr.send(formData); 
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 4)
                  if (xhr.status == 200)
                    var json_data = xhr.responseText;
                    window.location.href = xhr.responseURL;
        }
    }
        </script>

See: Accessing the web page's HTTP Headers in JavaScript

This article describes the methods to obtain String representations of all the headers, and a value for a named header: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest

DOMString getAllResponseHeaders();
DOMString? getResponseHeader(DOMString header);
