 Ping (blogging)


This article is about the web publishing mechanism. For the network test tool, see Ping.

In blogging, ping is an XML-RPC-based push mechanism by which a weblog notifies a server that its content has been updated. An XML-RPC signal is sent to one or more "ping servers,"[clarification needed] which can then generate a list of blogs that have new material. The technology was first introduced by Dave Winer to Weblogs.com in October 2001. Today, most blog authoring tools automatically ping one or more servers each time the blogger creates a new post or updates an old one.

Open ping servers, like Moreover Technologies' Weblogs.com, let other web services subscribe to a list of blogs that have recently pinged them. Blog search engines can provide fresh results very quickly by polling only the newly-updated blogs. Similarly, aggregators use results from ping servers to tell subscribers which items on their subscription lists have fresh material.
