cookies- PHP/Javascript - verify page

cadams

I am mainly fishing for some ideas about how to proceed.

I have a Windows server running IIS that hosts a service that users need to login to with their username and password.
The main web site lives on a Unix server and utilizes php for alot of the pages.
I would like to create some disclaimer/warning/alert so that a user must click on "I Agree" (it assumes that they have read the information on the page) before they can go to the logon page hosted on #1.

My idea was that the submission of the "I Agree" button would set a cookie. The cookie must exist for the user to be able to go to the login page.

These 2 servers are in the same domain. I assume that any cookie handling on the Windows server would have to use Javascript.

Can I set the cookie on the Unix server with PHP and then read it on the Windows server with Javascript.

Any ideas about how to proceed would be most helpful. I have done some coding in PHP and understand how to deal with Cookies. I am not real adept at Javascript and am in the process of reading about Cookies.

Cookies sit on the users machine ... not the server. You may be thinking of sessions, which do reside on the server.

Sessions are not accessible cross sites - not even from HTTP to HTTPS on one site.

You could have the agreement page on the *nix server be a form that posts to the windoze server.

just my 2 cents

Yeah, I didn't really mean setting the cookie on the server (*nx), but rather how to read the cookie that has been set via a page (the agreement page) on Server1 to allow the user to access a login page on the other server (Windows), Server2.

I am trying to prevent users from going through the "back door" to log in, as many already have that page bookmarked. Thinking this through, it would seem that when the user goes to the login page on Server2, the code should look for the cookie that was set when the user accessed the Agreement Page on Server1.

If the 2 servers are server1.doman.com and server2.domain.com and the cookie is set when accessing the Agreement Page on Server1, I understand from documentation that when the cookie is specified (in the Agreement Page code), it can be across the domain.com domain and these pages could "talk" to one another when looking for the cookie.

Please bear with me as I am just looking for clarification before proceeding. I can post some code later.

I just read that if you set the domain attribute of the cookie to .domain.com and your sites are foo.domain.com and bar.domain.com the cookie will be accessible by both foo and bar subdomain.

You could just test for the check box and redirect to the login page if true:

<?
$check=$_POST['checkbox'];
if($check){
header("location: login.php");
}
?>

You could install PHP on the Windows server, then handle the whole thing as a PHP project.
