can use the networks within the Internet operated by various Internet
service providers (ISPs) as a mechanism to deliver our organization’s
Web-server-based information in a timely and efficient manner to both
actual and potential users located around the globe. Last, but certainly
not least, we will examine how we can code Web pages to facilitate the
delivery of various types of media in an effective manner. In doing so,
we will periodically refresh our knowledge of HTML coding as well
as turn our attention to the number of bytes required to deliver certain
types of media. Many cell phone operators as well as Wi-Fi hotspot
operators are placing limits on the amount of data that can be delivered
for a basic monthly fee. With ISPs now billing companies based upon
traffic generated, additional usage is costing considerably more. Thus,
it is becoming beneficial to optimize the delivery of content for both
the recipient and the generator of such information.
As a professional author who writes on technology-related topics,
I am interested in and highly value reader feedback. You can write
me either via my publisher, whose mailing address is in this book, or
you can send an e-mail directly to me at
[email protected]. Let me
know if I spent too much or too little effort covering a particular topic,
if I should have included another aspect of content delivery network-
ing in this book, or share any other comments you wish with me.
Because I frequently travel, I may not be able to respond to you over-
night, but I will make every effort to respond to your comments within
a reasonable period of time. Many previous comments and suggestions
concerning other books I have written have made their way into subse-
quent editions, it’s quite possible that your comments will have a role in
shaping the scope of coverage of a future edition of this book.
