This is a PubSubHubbub 0.4 server. You can use it to instantly notify feed subscribers about updates.
To notify this hub that one of your sites changed, send a HTTP POST request to http://phubb.cweiske.de/hub.php:
$ curl -d hub.mode=publish -d "hub.url=http://blog.example.org/feed" http://phubb.cweiske.de/hub.php
This hub will then notify all subscribers about the update.
This hub supports additional notification modes.
If you do not know which of your pages did change - only that some of them did change - you can pass a wildcard URL (with *). phubb then checks all subscribed URLs that match the wildcard for changes and then notifies the subscribers:
To enable feed readers to detect that they can get updates via PubSubHubbub, you have to send two HTTP Link headers along with your files.
The first is a Link header pointing to this hub:
Link: <http://phubb.cweiske.de/hub.php>; rel="hub"
The second is a Link header containing the full URL of the site itself:
Link: <http://blog.example.org/feed>; rel="self"
Only if both HTTP headers are available, feed readers and other subscribers will be able to get updates via this hub.
phubb is a PubSubHubbub server written by Christian Weiske and licensed under the AGPL v3 or later.
