And here is the objective:
Alter your Acme, Inc. download interface from the previous lesson(I
had to not to allow users on computers straing IP with 202 and allow
only IE for Win and FF for Mac to download file) so that each user
must register her email address in order to download the file. Use
cookies to detect whether the user has already registered, and to
ensure that the user downloads the file only once within 7 days of
registering.
As always, validate the forms, comment your code, and explain your results!
