protected String[] buildPermissions(HttpServletRequest request, String[] configuredPerms, String action) {
        return buildPermissions(configuredPerms, action);
    }
Returns a collection of String permissions with which to perform a permission check to determine if the filter
will allow the request to continue.
<p/>
This implementation merely delegates to {@link #buildPermissions(String[], String)} and ignores the inbound
HTTP servlet request, but it can be overridden by subclasses for more complex request-specific building logic
if necessary.

@param request         the inbound HTTP request - ignored in this implementation, but available to
                       subclasses for more complex construction building logic if necessary
@param configuredPerms any url-specific permissions mapped to this filter in the URL rules mappings.
@param action          the application-friendly action (verb) resolved based on the HTTP Method name.
@return a collection of String permissions with which to perform a permission check to determine if the filter
will allow the request to continue.
