> When a request gets forwarded to another Servlet, {{HttpServletRequest.getQueryString()}} returns null, even if the original request contains query parameters.
> From Servlet 3.1 spec 9.4.1:
> {quote}
> The request dispatching mechanism is responsible for aggregating query string parameters when forwarding or including requests.
> {quote}
> The attached sample project demonstrates the problem:
> If you request {{/first?foo=bar}}, the corresponding servlet will forward the request to {{/second}}. The second servlet will get these values:
> {code}
> request.getRequestURI():      /forward-query/second
> request.getParameter("foo"):  bar
> request.getQueryString():     null
> {code}
> In JBoss AS 7.1.1  and Tomcat the result looks like this:
> {code}
> request.getRequestURI():      /forward-query/second
> request.getParameter("foo"):  bar
> request.getQueryString():     foo=bar
> {code}
