We're doing some server side device detection and need to drive ipad mini users to one page and ipad users to another.
Is there any thing that differentiates the two user agents?
iPad
Mozilla/5.0 (iPad; CPU OS 7_0_3 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11B511 Safari/9537.53`
Mini
Mozilla/5.0 (iPad; CPU OS 7_0_4 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11B554a Safari/9537.53
The only thing I see is the Mobile/11B511 and Mobile/11B554a, but is that a persistent value that we can work off?
Trying to do a device detection these days is hard and not reliable. I would recommend you instead of device detection to do a detection based on browser capabilities like I described it here.
Using this approach you are interested only if the browser supports a feature and you don't care about the device name/vendor.

How can I guess what kind of a machine i'm dealing with when running webgl?
Could I query something like MAX_VERTEX_ATTRIBUTES, OES_texture_float and other such properties and guess if it's a more high end or lower end GPU?
I think a better way would be looking at user agent string (navigator.userAgent), WEBGL_UNMASKED_VENDOR and WEBGL_UNMASKED_RENDERER from WEBGL_debug_renderer_info to try to figure out user's platform (mobile or desktop) and GPU (from WEBGL_UNMASKED_RENDERER).
E.g., here's my UA and renderer name:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/603.1.30 (KHTML, like Gecko) Version/10.1 Safari/603.1.30
Intel Iris OpenGL Engine
From that you can guess that I'm running a desktop Mac (Intel Mac part of UA) that has Intel iGPU (from renderer).
Another example, from an iPhone:
Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_2 like Mac OS X) AppleWebKit/603.2.4 (KHTML, like Gecko) Version/10.0 Mobile/14F89 Safari/602.1
Apple A9 GPU
From that you obviously can detect, that you're dealing with an iPhone 6S (since it has A9 chip).
Similarly you can detect Androids and WinPhones and query GPUs.
I'm parsing s3 logs to identify requests made from iMessage previews (on Mac OS Sierra & iOS 10).
There are few common types of UA strings, but I can't tell which are from the browser vs. imessage. I'm hoping it's a unique UA from Safari:
`AppleCoreMedia/1.0.0.14B100 (iPhone; U; CPU OS 10_1_1 like Mac OS X; en_us)
^ Gotta be iOS Safari, right?
2.MobileSMS/1.0 CFNetwork/808.1.4 Darwin/16.1.0`
^ I think MobileSMS means imessage (hopefully)
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.1.32 (KHTML, like Gecko) Mobile/14B100 Twitter for iPhone
^ Twitter via webkit webview?
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/54.0.2840.91 Mobile/14B100 Safari/602.1
^ more iOS Chrome (i see you CriOS)
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0 Mobile/14B100 Safari/602.1
^ more iOS Chrome?
Twitter/5002568 CFNetwork/760.6.3 Darwin/15.6.0 (x86_64)
^ Twitter
I've just faced the same issue while trying to re-route the iMessage crawler to a non-angular page which will generate the correct meta tags for it and found this question in the process. Figured I'd write an answer since I've now found it. Apple's documentation says nothing but mention the ...(Applebot/x.x) User-Agent which is not the correct one. I've found nothing on the internet so I logged traffic to just one file on a public server and shared the link via iMessage. In the log file I received:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/601.2.4 (KHTML, like Gecko) Version/9.0.1 Safari/601.2.4 facebookexternalhit/1.1 Facebot Twitterbot/1.0
When I've modified my RegEx to fit this User-Agent, the iMessage crawler was finally re-routed to the correct location.
So there it is, it's probably subject to change without notice since it does not exist in any official Apple documentation as far as I can tell but I hope this still helps someone :)
Use this regex to identify requests from IMsg crawlers.
(Twitterbot(.*)facebookexternalhit)|(facebookexternalhit(.*)Twitterbot)
I have tested it and it works perfectly.
I recently notice that approximately 17 % of users with ios device have browser with strange user agent. This user agent like the Safari user agent but with slight modification: it does not contain "Safari/XXXX" string.
Example:
normal user agent of Safari:
Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5355d Safari/8536.25
user agent of browser that i talk:
Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5355d
Can somebody explain me, how it can be? Which browser have this strange user agent?
The shorter user agent comes when an ipad enters "web app" mode. This means that a phone is parsing the html only using webkit, in full screen mode, not within a safari browser window. Thus only the information about CPU version, webkit version, etc is sent along.

Additional discussion can be found on this very similar post:
ipad user agent changes during use?
I would like to know how can I detect that my web application is running trough an iPad device, so I can do some code for iPad devices on my web application.
I'm developing a web application in .NET with C#, SQL Server and Visual FoxPro as databases.
The iPhone and the iPad both have distinct user agents.
An example would be
(iPad; U; CPU iPhone OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B314 Safari/531.21.10
You can find more information and some sample code in How to Identify an Apple iPhone, iPod or iPad Visitor to Your Website.
Is it possible to get the model information of an iPhone hitting a web page? I've looked at the User Agent, but it doesn't seem to have this information encoded within it. Essentially, I want to do this but from a browser.
They do have different user agent strings. iPhone 4 is
Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7
