This book teaches the essentials of working with the most important web technologies. From client development using HTML and Javascript, through to full server side applications written in ASP and Perl, the complete web system is shown. Concentrating on immediately useful code rather than theory, this is a how-to book for practical and project based courses. The broad scope covered by this book begins by creating reasonably simple webpages with HTML, then working through related document and content tagging systems such as dynamic HTML and eventually XML.
