When an Activity is received (i.e. POSTed) to an Actor's outbox, the server must:
|
|
|
|
0. Make sure the request is authenticated
|
|
1. Add the Activity to the Actor's outbox collection in the DB
|
|
2. Deliver the Activity to the appropriate inboxes based on the received Activity
|
|
This involves discovering all the inboxes, including nested ones if the target
|
|
is a collection, deduplicating inboxes, and the POSTing the Activity to each
|
|
target inbox.
|
|
3. Perform side effects as necessary
