If you plan to run your Web scripts under mod_perl, visit http://perl.apache.org/ for distributions and instructions.

Many of the scripts in this book use additional Perl modules besides those listed in the previous section. Some of these modules (such as IO::File or Time::Local) should be present in the standard Perl distribution. Others may not be installed and you ll need to obtain them:

• Business::CreditCard

  This module contains routines for checking credit card numbers. It s used in Chapter 10, E-Commerce Applications.

• Crypt::CBC

• A cryptography module used for encryption in Chapter 9, Security and Privacy Issues. This module isn t used by itself; you ll need another subsidiary module to go along with it, such as Crypt::Blowfish, Crypt::DES, or Crypt::IDEA.

• Digest::MD5, Digest::HMAC_MD5, Digest::HMAC_SHA1

  Modules for generating checksums, as discussed in Chapter 9, Security and Privacy Issues.

• Apache::Session

  Needed to provide session support for applications in Chapter 8, Session Management, and some applications in the following chapters.

• Image::Magick

  Used to produce image thumbnails in Chapter 5, Writing Form-Based Applications. If you install the C source distribution of ImageMagick, it may install the Image::Magick Perl module for you.

• Mail::Sendmail

• Gives scripts the capability to send email. It doesn t use the UNIX sendmail program, so it works under Windows, too, and is useful for generating mail on a cross-platform basis.

Several scripts in this book are written with the intent that they be run under the UNIX cron job-scheduling mechanism. For Windows, a free version of cron is available at:
