Subject Re: Off topic:cookies nightmare!!!!!!!!
Date Mon, 29 Apr 2002 21:42:13 GMT

I had a similar problem, which seem to be resovled by explicitly setting 
the path of the cookie to "/" before adding it to the response.

    Cookie userCookie = new Cookie("U_ID", userId);

After reading the Servlet docs, it seems the behaviour for setting a 
cookie without first setting it's path is undefinded. I've found that 
with Tomcat, new Cookies use the current URL of the request instead of 
the "/" when a path is not specified. I also believe there may have been 
a few bugs with previous versions of Tomcat and Cookies which have been 
resolved with newer versions.

Hope this helps,
