i know these post are now about 4 month old
so i would love to know if you managed to create a push_module for ejabberd ?

i am very new to ejabberd / erlang but i am thinking of making a chat client for the iphone too

if i am right you are trying to send apple the push notification each time a offline msg is received,
as far as i know apple dosent like those many requests or did you implement some kind of buffer in php ?
and wouldnt it be possible to send the request to apple directly through the push_module ?

if you didnt manage or didnt have time i would use your attempt as a starting point for me

I offer you an idea, but I

I offer you an idea, but I don't have more minutes or hours to help you. If you read this idea, you agree to not ask me any more details.

It's possible to write an ejabberd module that adds a hook to the event offline_message_hook. When the hook is executed, the associated function can do whatever you want: send a message stanza to another user, make an HTTP query to a remote machine...
