I'm not sure I understand-- I want to check to see if their page has
changed once each day and, if so, I will highlight that link in my list...
I doubt most web sites would have a problem with one hit per day :)
I am not scraping and redisplaying content...
My question boils down to the most efficient method to detect whether a
page has been modified recently...
