good point... what I found is this (this is the correct part is it not?):
// format of id is <random-hex-string>.<count>.<timestamp-ms>
static synchronized private String getIdentifier () {
String random =
Long.toHexString(Double.doubleToLongBits(Math.random()));
String time = Long.toString(System.currentTimeMillis());
session_count++;
return random + "." + session_count + "." + time;
}
not that complicated... but from what I read about the Random object in Java
(which is used by the Math.random() method) if two rand. number generators
are created with the same seed they would produce the same random numbers..
but since you get the time that seems to make it hard to guess it...
