Regex detect Iphone App User agent (not web browser from Iphone) in Ruby

Question

I have to differentiate between an incoming request from an Iphone App and an incoming request from an Iphone/Ipad (apple mobile device) web browser.
As stated in this question Iphone Web Browser vs Iphone Web Agent and for what I have seen in my logs, the difference between both user agents is that when coming from a web browser, the word "Safari" is added at the end. So my question is:

How would I create a regex similar to this one:

/Apple.*Mobile.*Safari/

But instead of .*Safari, making sure that Safari is not there. So I know the petition comes from the app.

Yes, I have heard of it, but I would love to hear more, or suggestions on how to deal with this. — Hommer Smith, Mar 20 '12 at 17:35

You could do it with en expression like:

Apple.*Mobile(?!.*Safari)

Thanks for the quick response. But what if I would like to know that Safari doesn't exist AFTER Mobile? – Hommer Smith Mar 20 '12 at 17:34
