Abstract

A request for a partial update of web content is received that identifies at least one web content element associated with the web content. An update is requested for the identified at least one web content element from a content server. The partial update of the web content is performed in response to receipt of the update for the identified at least one web content element from the content server. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
