        Thanks, Darryl.  Yes, that much I do know about TLS.  I just didn't 
know if I needed to update anything on my end in the code.  I don't want a 
bunch of angry emails from customers saying their cart's broken the day after 
the switch. ;)  From your answer, it doesn't sound like I need to change 
anything.

        However, what if someone is still on Perl 5.8.8?  That's older the last 
5 years.  Will that even make a difference?  Where is TLS actually handled - in 
Perl, in the code, in the browser, on the server?  This is the part that has me 
stumped.

Thanks again,
Frank
