Openresty + socket + ssl question

I see, so there is no way to do this purely via ngx_lua, for now? :(
I`ll try to use standalone server to send APNs first, this is just
faster way to start testing our application.
But i will be glad to test out ssl support in OpenResty when it will
be available :)
Thanks for great product!
