7 *NOTE: THIS MODULE IS RELEASED UNDER THE MOZILLA PUBLIC LICENSE VERSION 2.* |
2161 | 8 |
9 Normally the XMPP server will store and maintain the users' contact | |
10 rosters. This module lets you delegate roster management to an external | |
11 service. | |
12 | |
13 Prosody will make an HTTP request to fetch the roster from the external | |
14 service. The service will need to notify Prosody whenever a user's roster | |
15 changes, so that Prosody can fetch a new roster for that user. | |

22 `VirtualHost` is being configured, add the following: | |

81 ### Notifying Prosody of roster changes |
2161 | 82 |
83 The external service needs to notify Prosody whenever a user's roster | |
84 changes. To do this, it must make an HTTP POST request to either: | |

89 Make sure that the "http_files" module is enabled in Prosody's configuration, | |
90 for the above URLs to served. | |
91 | |
92 Ports 5280/5281 can be firewalled and the web server (i.e. Apache or Nginx) | |
93 can be configured to reverse proxy those URLs to for example | |
94 https://example.org/http-bind. | |
95 | |
96 The contents of the POST should be a JSON encoded array of usernames whose | |
97 rosters have changed. | |
98 | |
99 For example, if user ‘john’ became friends with ‘aaron’, both john’s | |
100 contact list and aaron’s contact lists have changed: | |
