In blog sites context, this mechanism consists in send an specific message to other site every time a new post has been published. There are plenty of reasons to use this, and they lay over your needs and the service provided by the remote host. For example, notifying web search engines that your site has new content, or send a tweet to your followers to let them know that there is something new to read.

This feature is implemented in b2evolution by the ping plugins. If you want to read more about this kind of plugins included in the standard release, please go to:

Please note that b2evolution will automatically avoid pinging from local sites installed for tests purposes (http://localhost, http://mysite.local, etc), unless you set the following config variable in _advanced.php or better yet _local.php:

• b2evo 6.8.2 and below: $test_pings_for_real = true;
• b2evo 6.8.3 and above: $allow_post_pings_on_localhost = true;
