在一个Java过滤器设置响应头位置解决了这个。

Solved this by setting the response header "Location" in a Java Filter.

  HttpServletRequest httpRequest = (HttpServletRequest) request;
  HttpServletResponse httpResponse = (HttpServletResponse) response;
  String path = httpRequest.getRequestURI();
  httpResponse.setHeader("Location", path);

在JavaScript中，我可以再使用

In JavaScript I could then use

  XMLHttpRequest.getResponseHeader("Location")

希望这不会造成任何不可预见的问题。 ：P

Hopefully this won't cause any unforeseen problems. :P

如果任何人有一个简单的解决方案，虽然我想看到的。

If anyone else have an easier solution though I'd like to see it.
