Problem reading a cookie from within a tracking pixel in IE

I wrote a simple pixel tracking program that works something like this

Step 1) tracker.com sets a cookie
Step 2) mysite.com displays <img src="tracker.com/tracking.php">. That image reads the cookie from Step 1 & does some processing.

Works great in Chrome, Firefox and Safari. But when tested in IE, the cookie can't be read in Step 2. It's as if the cookie doesn't exist -- but I know it does.

Any idea why IE pretends the cookie doesn't exist? I've tried messing with P3P headers, no luck.

So, the first answer was more about testing... try using JS to handle this -

From site-reference.com forums..

<script type='text/javascript'>
var track = new Image(); 
track.src="http://www.my-site.com/tracker.php?self=" + this.location;
</script>

*NOTE: Capital "I" in image, not lowercase!

Let us know! :D

Does your domain have a privacy policy? I forget what it's called, maybe p3p? Some random list of headers that you have to add.

Its tricky without knowing more specifics of its use, but I'm trying at this late hour to figure out how to clone the cookie for the current domain using REMOTE_ADDR

It may be that IE is blocking 3rd-party cookies.

If the cookie setting domain is 2 letters, I believe there is a bug within IE that prevents IE from doing cookies properly with 2 letter domains. If it isn't 2 letters, then nevermind.

Try adding the domain in the src attribute to trusted sites in IE. My guess is this is security, and you've got a rather arcane security measure you're coming up against.
