I've seen similar questions on this issue, but they are related to native apps. I build web apps for the iPhone/iPad that run in the browser (Safari).

I was wondering if there is a way to prevent orientation change in the browser, perhaps via some meta tag. I know of the viewport meta tag which allows you to specify scale and zooming capabilities, so figured maybe there is something similar for orientation.

I doubt it is possible, but I thought I'd just pop a question on here to see.
