Domain configured in Vpn on demand doesn't automatically enable vpn

[venth]

Hi, I've configured 2 domains that need connection secured by vpn. Unfortunately vpn connection isn't automatically enabled when I use safari to reach webpages provided on these domains. How does this feature should work?

This feature is not reliable enough yet. As I tested in iOS 9 and iOS 10, sometimes it does not work as expected.
