Refresh APNS Connection #11

Open bisikli opened 5 years ago

bisikli commented 5 years ago

Hello,

APNS service has a known. bug that, if you send a request in a session which stays idle for a while, APNS service returns an internal server error such that : "500 Internal Server Error: Unable to write frame"

Other push services overcome this problem by refreshing their APNS connections when they encounter this kind of a problem. (for example: https://github.com/relayrides/pushy/pull/529)

Is there a way to refresh connection in Perfect Notifications?

When it goes to send msgs to an existing connection, the library will first try a PING to ensure the connection is still good. If it's not it will open a new one.
