Make checkOrigin also available under non-android/ios scenario

[tymaoa2]

Hi, it is sweet to see that checkOrigin func implemented, which help user setup multiple effective origins, but only limit to android/ios devices.
(The code looks like this, if i do not misunderstand it)

Is it possible to remove the limitation that only ios/android devices can be applied? For two reasons:

1. User have devices other than ios/android.
2. For web scenario, there also have multi-origins setup needed, like a web services under mutiple ccTLDs:
