Re: stupid crosscookie function

That's correct. You can have pages at site1 and site3 that get a cookied-image from site2, and site 2 can track activity across those sites (look at the referrer, etc.), but site1 and site3 still can't read the cookie directly. Where I've set up a cross-domain cookie server, the site that serves the image has to be a proxy and hold the cookie on behalf of the other sites. They can then exchange data through some back-channel (i.e. a common database or request broker). For example: site1: ... <img src="site2.com/setcookie.php?user=12345"> Site 2 sets a proxy cookie with info about user 12345 and stores info in a database. If the user subsequently goes to site3, a page at site3 can ask site2 to return the user associated with the cookie. I hope that's clear...it's been a looong day. :) It's an awkward process, but it's possible. - Tim > I use images: but cannot grab the cookie from the image that points to the > other site. > > Site 1 > <body> > <img src="http://site2.com?setcookie.php3"> > </body> > > Cookie is set on site2, not site1
