Cookie experts, please help!

Ok, i've researched this several times and cannot find a solution.

I need to set a cookie on one domain and be able to access it from another domain. I have tried changing the domain in the setcookie function but of course, due to many security issues with that, it does not work.

This is what I was thinking of...

On domain1.com there would be a code to execute a script on domain2.com. When the script executes it sets a cookie on domain2. The reason for this is because the script must be on the server it is setting a cookie on.

Is there any way to execute the script on domain2 from domain1?

Does anyone have any ideas how this can be done?

Yes, it is possible, anything is possible. If there is a will, there is a way. I have actually seen this done many times. Any help/suggestions is appreciated.

also, Yes, it does have to be a cookie 🙂

Thanks,
Matt

The only solution I have been able to get to work was have a small window popup from domain1 to domain2. This does work but with all the popup blockers and all the people leaving javascript disabled this really is not an option.

somethings are just not possible, such as trying to read a cookie not made by the same domain 🙂

you can execute a script by creating an cronjob on which ever domain that runs a file, say cronjob.php had the code you want to run ... make a job that runs this file on the second domain.

Could the script on domain2 be executed via the command line (exec) from domain1?

if php is installed with a cgi version, maybe, if not NO

I know you cannot read a cookie not set by the current domain, this is why I want to execute a script on domain2 from domain1. The script on domain2 will set the cookie with a variable in the command line.

http://domain2.com/setcookie.php?cookieval=$value would be executed from domain1.com

why does it have to be via command line?
the easiest and hassle free way is putting the script in a secure directory and having the other server call it via shell_exec() or exec()..

The problem with that is I cannot execute a shell command from domain1 on domain2, the script would have to be on domain1 and the cookie would not be set for the correct domain. : )

I have found a solution that will work for my current project, but it is not 100% what I wanted.

Well it wasn't what I wanted but I put a redirect on domain1 that sets the cookie then redirects to domain2. For the current project i'm working on this will work fine for about 90% of the traffic going to either domain. I will not work the way I wanted it to though
