Webbrowser..differences?

Whats the difference between...

Webbrowser1.Refresh and Webbrowser1.Refresh2
or
Webbrowser1.Navigate and Webbrowser1.Navigate2
?

[Gen-X]

I'm not sure what the difference is between the Original and the Original2 methods... perhaps newer versions or alternatives?

But I believe the difference between Refresh and Navigate is this.

Refresh will use the same HTML it retrieved from the webserver and "refresh" the display in the event things got messed up

While "Navigate" will actually go and ask the web server to send a NEW copy of the HTML so it can do it all over again.

Kind of like the difference between "Refresh" and "Reload" on your browser at the moment.
