[OmniFaces utilities (2.4)] Get the HTTP request URI, regardless of any forward or error dispatch


[OmniFaces utilities] The getRequestURI() method returns the HTTP request URI, regardless of any forward or error dispatch. This is the part after the domain in the request URL, including the leading slash.

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

Some use cases are available right in OmniFaces source code. For example, OmniFaces uses getRequestURI() to check if the given HTTP servlet request is a JSF resource request:

public static boolean isFacesResourceRequest(HttpServletRequest request) {
 return getRequestURI(request).startsWith(request.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER + "/");
}


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