[OmniFaces utilities (2.4)] Get the HTTP request query string, regardless of any forward


[OmniFaces utilities] The getRequestQueryString() method returns the HTTP request query string, regardless of any forward.

Method:
Use this one outside JSF context
(Servlets#getRequestQueryString())
See also: Utils.coalesce()
Use this one in JSF context
(Faces#getRequestQueryString())
See also:  Faces.getRequest() | Faces.getContext()
Usage:

Some use cases are available right in OmniFaces source code. For example, OmniFaces uses getRequestQueryString() to get the HTTP request URI with query string, regardless of any forward:

public static String getRequestURIWithQueryString(HttpServletRequest request) {
 String requestURI = getRequestURI(request);
 String queryString = getRequestQueryString(request);
 return (queryString == null) ? requestURI : (requestURI + "?" + queryString);
}
