View Full Version : Reading Data From Cookie

04-25-2008, 07:19 PM
I have created a basic form in JavaScript that asks for user data, I then store that data in a cookie. What I need is if the user comes back to the page and fills in the same data I want to re-direct the user to another page stating that has already been entered. Right now I know I am able to read the cookie because I put in a test message on page load to show me the data. I just don't know how to compare the data in the cookie with the data entered and then re-direct if the data matches....

this is posted in the wrong forum, this is the java/jsp (java server pages) forum not the javascript forum

Don't want to duplicate the thread, so closing.
