This event is fired each time an authorization request
is received from someone. The event provides two
parameters, Contact and Action.
The Contact parameter provides you with a
reference to XMPPContact object which is automatically
created by wodXMPP based on information known about
requestor.
The Action parameter allows you to decide
whether to allow or deny the request. Set this
parameter to Allow if you wish to allow user to put
you on his contact list. Otherwise set it to Deny.
Based on your Action parameter setting, wodXMPP will reply
to the server which will then add person to your Contacts
list, of will send refusal message to other contact.
Don't forget - you're allowing other side to see
when you're online and have you on their list. If you
want to see them too, you must ask them for authorization
using Subscribe
method.
