It's not a big deal to change the source - just trying to make 
minimal changes in order to keep up with future upgrades.

One other thought on ups_cache might be to store the 1st three digits 
of the ship-to zip code in the lookup table - this could save many 
entries from being added, especially if using www lookups on Ground, 
3 day, 2 Day and 1 day, etc.

I know this is not really an issue on 1 day cache expire, but with 
expire set to 30+ days - it will add up.

Thanks for your insight.
