the two things I see, are the setting of secure and not of path.

The urls you have do not look like they go over SSL, but:

If a cookie is marked secure, it will only be transmitted if the communications channel with the host is a secure one. Currently this means that secure cookies will only be sent to HTTPS (HTTP over SSL) servers.

If secure is not specified, a cookie is considered safe to be sent in the clear over unsecured channels. http://wp.netscape.com/newsref/std/cookie_spec.html

I believe that some/all versions of IE will not save a cookie if the path is not specified in the cookie.
