All iPads URL of Facebook when using FaceBook App

If I'm following your question correctly, it's not actually the browser opening.

Native iOS apps can open a "web view" in the app itself, with very specific control presentation (and make the web view appear chromeless).

Basically when you call native web content, but you want the user to experience it seamlessly in the app (very common, Twitter, most news/feed apps, etc.)

Yes, I wasn't clear.

The content within the "Web View" has the "Facebook Chrome" stripped out of it. This must becoming from either a different URL or some other flag that the Facebook website knows to remove certain content (such as Chat).

OK, yes, that's what I said above.

When you're in an app, and the app opens some "regular" web content without switching over to Safari, it does it through a UIWebView ... that's basically like an embedded browser, but minus all the browser chrome/controls/nav/etc.

It's handy for displaying web content while controlling the UX and keeping the user "in" the original app (and you can display some custom menu options).
