<c:url var="queryString" value="?${requestScope['javax.servlet.forward.query_string']}"/>

I know <c:url> is used for URL rewriting. But here from where the url value is assigned to the var queryString. I don't understand the meaning of requestScope['javax.servlet.forward.query_string']

From the documentation:

The name of the request attribute that should be set by the container when the forward(ServletRequest, ServletResponse) method is called. It provides the original value of a path-related property of the request. See the chapter "Forwarded Request Parameters" in the Servlet Specification for details.

The javax.servlet.forward.query_string parameter is being set when the

requestDispatcher.forward(request,response);

is being called from the controller.
