Abstract

A conversion server responsive to browsing requests issued by a browser unit operative in accordance with a first protocol is disclosed herein. The conversion server includes a retrieval module for retrieving web page information from a web site in accordance with a first browsing request issued by the browsing unit. The retrieved web page information is formatted in accordance with a second protocol different from the first protocol. A conversion module serves to convert at least a primary portion of the web page information into a primary file of converted information compliant with the first protocol. The conversion server also includes an interface module for providing said primary file of converted information to the browsing unit.
