URL Hack to See When Page Was Last Updated
Posted by MickeyMouse in Internet
I love quick little useful hacks. Using one line of javascript, you can see when the last time a web page was updated. Here is the code to paste into your address box…
Since I found this, I have been using it all the time. It turns out to be a lot more useful than I ever imagined.
I just did it as I am editing this tech-recipe to show you what it looks like…
Try it. Right now! 
Just paste this code into your address bar and hit ENTER:
javascript:alert(document.lastModified)
This code will display the last time any web page was updated and display it in a message box on your screen.

Works for me. It does not seem to work on dynamic websites such as ASP or .NET.
Just a theory but would make sense. The dynamic creation of the page would, I suppose, give it a modified date of “just now”
Try it with: http://www.atlanticgames.net, and then again once you log on
