Tip - finding last date updated

I found a scrap of paper in my briefcase . . . can't remember where I picked up this little bit of information, so here's an apology to whomever I should give credit.

If you want to know the last time a web page was updated, while that page is displaying in your browser, enter this text in the address bar:
javascript:alert(document.lastModified)

A small dialogue box will appear with the last date the page was uploaded. Note: this only works with .html pages.
