was set on your server to default to 1, it would automatically send a cookie. Since I am not seeing that behavior on every pageload, and it was a phpsession cookie, and I think your linksoftware MIGHT set a cookie, I think there must be a 404 somewhere -- perhaps even just favicon.ico which would be grabbed by your link script.

Since your rule sends every non existent file request to your link script, if any css, favicon.ico, image, background, etc is missing, you'll get 1 hit to your link directory, and, if the link directory sets a cookie, you're going to set a cookie when someone loads that page.

I am getting a straight 404 when I try to view your favicon.ico, which is possibly what Firefox triggered when it visited the site which prompted the cookie.

As for the save file as, take a look at firebug, its a firefox extension, or liveheaders. I would suspect that you are getting a Content-type: something that is different than what I'm seeing. If it is text/html, then, you have something else wrong somewhere.
