## Public Hub
|
|
|
|
|
|
|
|
|
|
By default, Shaarli will use [Google's public hub](http://pubsubhubbub.appspot.com/).
|
|
|
|
|
|
|
|
|
|
[Here](https://github.com/pubsubhubbub/PubSubHubbub/wiki/Hubs) is a list of public hubs.

You can also host your own WebSub/PubSubHubbub server implementation, such as [phubb](https://github.com/cweiske/phubb).

## cURL

|
|
|
|
|
|
|
|
|
While there is a fallback function to notify the hub, it's recommended that
|
|
|
|
|
you have PHP cURL extension enabled to use this plugin.
