Using yauaa to distinguish browser and thick app

[yyy]

I have a usecase where I want to distinguish requests that come from browsers vs thick apps. I need this for both desktop and mobile, but I was specifically testing on iOS and Android. I've observed that on Android, I'm receiving AgentType "Browser" for browsers, and "Browser WebView" for thick applications that embed WebView. But on iOS, AgentType comes as "Browser" for both.

What is the recommended way to find out if the request is coming from a browser or a thick app?

Do you have examples for all of these?

Sorry it took so long to respond. It looks like the latest version of yauaa is better than when I tried it...

Here are some user agent strings that we've collected:

SalesforceMobileSDK/9.1.1 iOS/14.8.1 (iPhone) Chatter/234.020(6203393) Hybrid uid_9325236B-A894-45E2-BA6D-F9B37FFC8423 ftr_ Mozilla/5.0 (iPhone; CPU iPhone OS 14_8_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 iPhone/14.8.1 iOS_iPhone Salesforce1/234.020(6203393)

These are all using a browser component inside mobile apps, but I understand that for some mobile apps the user-agent is identical to the browser user agent, and YAUAA won't be able to distinguish them simply based on the User-Agent.

The only one that goes seriously wrong is SalesforceMobile on iOS where AgentClass is reported as Browser (should be something else).

In the SalesforceMobileSDK on iOS (the Chatter thing) you see that it is classified as a Webview.
This is essentially a webbrowser which was embedded in an app.
So yes I agree: "Browser" doesn't seem right.

I improved this. Please check https://try.yauaa.basjes.nl/ if this is better.

I'm assuming this has been answered.
