updates - How to know when a webpage is updated?

I'm looking for some way to know when a webpage is updated. This site it's really not very "web 2.0", doesn't have ajax, it seems like plain HTML.

I need a way to get an instant notification when the page is changed/updated.

Is there any app. to do that?

Thanks

I ended up using NotiPage

NotiPage is a FREE webpages monitoring software. Once you've configured a monitoring alert related to a specific webpage, NotiPage will automatically check this webpage on a periodic basis until all the set criteria are met. At that time, NotiPage will warn you by a visual and audible alert.

Freeware, lightweight, recently updated. Can check every 1 minute.
