High Quality Content by WIKIPEDIA articles! Globule was an open-source collaborative content delivery network developed at the Vrije Universiteit in Amsterdam (2006). It is implemented as a third-party module for the Apache HTTP Server that allows any given server to replicate its documents to other Globule servers. This can improve the site`s performance, maintain the site available to its clients even if some servers are down, and to a certain extent help to resist to flash crowds and the Slashdot effect. As of February 2011 the project is discontinued and is no longer maintained.
