On one windows box, for sure, cookies were not set when using the header("Location: "); redirect. One fix was to generate a transition page with a <meta> refresh tag. Using the header("Refresh: 0; URL= "); solution is easier and cleaner.

It was a windows machine causing the problem... go figure.

Anyhow... the others that have reported this utility as not working were having problems on windows boxes. (I do believe they all were but I could be wrong)
