globals are just like variables in java.
-- Java 101 (not rules specific) ---
Please remember that java uses "pointers" (kinda) for objects.
If you set url to something, you are just changing that local label to point
to that literal, not its value.
THis is just standard java.
String url = "";
void doSomething(String url) {
url = "bar"; //this does nothing, as it just changes the url to point to
"bar" value. The url outside the method is of course unchanged.
}
