No it's not.

ContainerResource are reponsible for providing to their children (at
init time), their URL, eg in the DirectoryResource, the code looks
like:

DirectoryResource:createDefaultResource(..) {
...
	Hashtable defs = new Hashtable(10) ;
	defs.put("parent", this);
	defs.put("resource-store", children) ;
	defs.put("server", getServer()) ;
	defs.put("url", getURL() + name);  // HERE !
...
}
