Cookies across domains (WSC)

Anon

I have been working with cookies for the past two days using IE 6. I am having the following problem.

On www.domain1.com , I set the cookie in PHP like so...
setcookie ("CookieName", $Value,time() +3600); // 1 Hr. Expiration

It seems to work fine when retrieving the cookie on the same domain using a print command in a php page.

print "$CookieName";

However, the same print command in a php page on a different domain, ( www.domain2.com ) shows a blank variable. It will not read the variable on a different domain.

Is there a way to set a cookie using setcookie() to make it able to be read on a different domain??

Example:

www.domain1.php (Set Cookie)
www.domain2.php (Retrieve Cookie)

I have read every listing in the forum search here at phpbuilder.com and I have also read the PHP manual. But, I am a little lost here.

Thanks

Oops. in the example, I meant to say

www.domain1.com (Set Cookie)
www.domain2.com (Retrieve Cookie)

Cookies are specific to domain. Part of the cookie stored on the client computer is the domain name. If you need to transfer session information from one server to another you probably need to look into the serialize functions or other methods.

Right, but can you define the domain on which the cookie will be retrieved using path or domain?

setcookie ("CookieName", $value,time()+3600, "/", ".domain2.com"
);

I am not sure if this is possible, but have been wondering what the domain path is for.

Privacy concerns dictate that one domain cannot access another's cookies. This is documented in http://www.netscape.com/newsref/std/cookie_spec.html
under the domain heading. You can try to set a cookie for an arbitrary domain but most browsers will not (should not) allow it.

Thanks for the link to the specs.
