HI Al,

I've already accommodated the UI to be responsive. I have one set of code
for everything. It even switches to a mobile style browser once the
viewport shrinks to a certain value.

This specific use-case is for url redirects.

If someone creates a redirect, ie 'details.at/myNewBook' I'd like for them
to create specific redirects based on device, location, and application.

For location, I'm doing a simple IP lookup against a geoIP database.

For application, it's just adding a port number to the redirect.

But for device, I'm finding that I just have to parse the
cgi.http_user_agent for matches like 'Windows NT 6.1, Windows NT 10, Linux,
Android, iPhone' etc. etc.

I know that can be spoofed, but I think it's about the only semi-reliable
'non intrusive' way of determining the device type.

-Jason
