HELP! Cookie to remember and redirect on the click of a button
Hi all,
I'm not a javascript expert, please help me.
I need a script that will do:
1. The index will have 2 options, option 1 takes you to Page1, option 2 to Page2
2. When the user will visit the page again it will redirect them to the page of their previous option.
I've been looking for hours and I can't find what I need.
Found the following script which is almost perfect
http://javascript.internet.com/cooki...-redirect.html
But when you make your selection you have to reload the page in order to work. I don't think that this is very good.
Is there a way to alter the code and add a button instead of having to refresh the page?
please please help
many thanks

I'm not a javascript expert, but a page redirect can be used as follows . . .
<meta HTTP-EQUIV="REFRESH" content="0; url=http://www.gohere.com/index.html">

optional page load
I think the page has to load again, no?
On initial load - if cookie ? use option : show set cookie button
How would the page load the first time based on a cookie that hasn't been set yet?
Maybe you could do someting with AJAX that would do what you're looking for?

Thanks for your reply
but you either didn't read my message or I didn't explain my self correctly.
I will explain again...
Index page with 2 options (Page1, Page2) with check or radio buttons and a 'Go' button.
The user must choose between the two options in order to continue the navigation.
Lets say he chose option 2(Page2) and pressed the 'Go' button...Fantastic
The next day the same user after he will type the url, the index page must remember his choice (with the cookie) and redirect him to Page2 which was his choice.
I hope it's more clear now.
Thank for taking the time to read my message.

cookie redirect
It looks like the script sets a 30 day cookie. Do you have your browser set to delete cookies when the browser closes?

No my browser doesn't delete cookies.
The script works fine I just want instead of hitting the refresh browsers button to have a button to click on.
