We have a large, commercial WebDirect app. We would like to have a cross-platform mobile version for a few of the screens. Ideally, we'd like to be able to detect the mobile browser (Safari or Chrome) and present mobile-friendly WebDirect layouts for simple data update functions when the user clicks on the link in the notification email. Has anyone done this? Is there a way to distinguish between the desktop and mobile versions of these browsers? Any way to detect portrait or landscape mode in the browser? Any other "gotchas" I should be aware of? Any input would be appreciated.
