Passing UDO object value in Generic script tag's URL?

[nickmv]

Is there a way to reference/pass a UDO object's value inside the URL for a Generic Tag that uses a script.

So I have a generic script tag going to site.com/p.ashx?var=[needUDOhere], and I want to pass back a UDO value when the script tag fires.

Any ideas?
