I need you to create a cookie that does this:
First of all I have a web page with an aweber optin box on it.
If someone fills in this box and gives me their email address I send them a free download.
However, I do not want someone who has already opted in to my aweber form to be able to return to my web page and enter in email addresses in the box again.
I want someone to create a cookie that recognizes when someone has already opted in on my aweber form.
Instead of letting them see the aweber form again it redirects them to a different page on my site.
I don't know how to install/activate the cookie, so I will need you to explain what I have to do.
This site uses the same function that I need.
Once you enter in your email address in the box, whenever you return to the same web address you no longer see the email optin box page and are taken to another page in the site.
