Both answers are correct. But here is a little bit more. UPDATE: -- Masem did catch that -- man, I am missing things today.

Some versions of Netscape do not support setting cookies at just http://corn.com/ . For historical reasons (that I used to understand), they require you to have something like www.corn.com or anysubdomain.corn.com before it will allow you to set the cookie. That is the reason you might have got .corn.com to work.

Today, most modern browsers allow for setting cookies at http://corn.com/ . Unless you are writing primarily to linux users where the percentage of Netscape users is far higher than the rest of the traffic on the web (85 to 95 percent of traffic to our 8 million hit a day site comes from Internet Explorer) then it isn't too much of a concern. If you do need it to work on Netscape, try bouncing them to a www.corn.com domain first, before setting the cookie and all should be well.
