             Summary: HttpServletRequest.getQueryString() returns null for forwarded requests
                 Key: WFLY-2284
                 URL: https://issues.jboss.org/browse/WFLY-2284
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 8.0.0.Beta1
            Reporter: Christian Kaltepoth
            Assignee: Stuart Douglas
         Attachments: forward-query.zip

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}
