I have a site that runs on apache port 80,

it runs like


that sets a cookie.

I'm retrieving the cookie in a java app, that runs in a tomcat, port 8080.
So i have

 However, the cookie is NOT being sent to teh java app by Firefox, chrome opera..only by IE 6.
Why is this?

I understand that cookies are shared in the same domain, Are ports taken into account?
Links to "official" documentation will be appreciated.

ports are part of the host value, so if you are not careful they can find their way to the cookie. for example, the javascript location.host value contains the port number.

get the TamperData addon to firefox and see what exactly passes between server and client.

After installing th eplugin, I realized that the cookie was Being sent to the server, and that it was an error in my code (which only fails when deployed to the server). My fault, but thanks for the plugin suggestion!
