App to check webpages for changes?
I'm looking for a small app, preferably in unix that would check a list of webpages to see if they have changed since they were first indexed.
It would be wicked if it could use a proxy list.
If I can't find one that's free/cheap, I'll probably just code one myself. I just thought someone might have done it already and it's on sourceforge or something.
