This is a weird one.

We have a production server (Server 2008) and two staging servers (Server 2008 and Server 2003)

I have sites on all of these. They all use cookies.

On the Production server when browsing to our site www.supernovainteractive.com there is a cookie that detects when you visted the site and it will not refresh the logo animation (top left hand side) on clicking to another page. This works for all browsers on the production server. I’m not sure what’s going on but for some reason cookies are not working on one site in the 2008 staging server only. This is when browsing using Firefox (3.6.3) they work fine on all other browsers (IE, Chrome, Safari, Opera) In addition, the 2003 staging server works fine. You can test on the Supernova Interactive site by noticing the logo in the top left corner. It uses a cookie to detect if you’ve already seen the animation. Once you’ve seen it once, it doesn’t animate again until tomorrow. Currently, it’s animating every time.

I have opened an outside facing port so others can see the issue. Http://exchange.supernova.com:10009

Any ideas on this one? Firewalls are off on the server. Notice you do not get a cookie from Exchange.supernova.com.
