// This script was modified for use with high traffic sites, there are three major modifications
// 1) It tacks on a 'random' # to the end of the tracking call to cachebust
// 2) It only tracks unique visitors when VwptCountRepeat is false
// 3) It uses random #'s to send back tracking on only some subset of the total hits
