I have found some sections in this book a real help and others not so helpful. Html,javascript,perl,cgi are well covered as the author goes into good detail with lots of examples but i was a little disappointed with some of the other areas of the book in particular the php section where he mostly justs shows the difference between php and perl the languages are similar but i think php should have been covered in more detail as it is growing and growing in use. This book will help you to get building websites using html,javascript and provides a solid platform using perl for cgi programming but is not the complete interent programming book and to the authors credit he does acknowledge this. So for some of the more advanced subject areas jsp,asp this book wont be the most useful resource to use.
