mod_s2s_keepalive: Use timestamp as iq @id RFC 6120 implies that the id attribute must be unique within a stream. This should fix problems with remote servers that enforce uniqueness and don't answer duplicated ids. If it doesn't do that, then at least you can get a guesstimate at round-trip time from the difference between the result iq stanza and the timestamp it was logged without having to go look for when it was sent, or needing to keep state.

summary: Subscribe to Atom and RSS feeds over pubsub
---

# Introduction

This module allows Prosody to fetch Atom and RSS feeds for you, and push
new results to subscribers over XMPP.

# Configuration

This module needs to be be loaded together with
[mod\_pubsub][doc:modules:mod\_pubsub].

For example, this is how you could add it to an existing pubsub
component:

``` lua
Component "pubsub.example.com" "pubsub"
modules_enabled = { "pubsub_feeds" }

feeds = {
  -- The part before = is used as PubSub node
  planet_jabber = "http://planet.jabber.org/atom.xml";
  prosody_blog = "http://blog.prosody.im/feed/atom.xml";
}
```

This example creates two nodes, 'planet\_jabber' and 'prosody\_blog'
that clients can subscribe to using
[XEP-0060](http://xmpp.org/extensions/xep-0060.html). Results are in
[ATOM 1.0 format](http://atomenabled.org/) for easy consumption.

# PubSubHubbub

This module also implements a
[PubSubHubbub](http://pubsubhubbub.googlecode.com/svn/trunk/pubsubhubbub-core-0.3.html)
subscriber. This allows feeds that have an associated "hub" to push
updates when they are published.

Not all feeds support this.

It needs to expose a HTTP callback endpoint to work.

# Option summary
