Could someone please tell me how cookies are scoped and managed? I have a web application, implemented with Tomcat, and in some parts of the application I can get cookies, and in others not. The header HOST value is the same (I've printed it out), so I don't know how to get at these cookies.
What I'm trying to do is implement an autologin type feature. When the user logs on manually (via a page like "http://host.com/login.jsp"), the user is validated via a database lookup in a servlet and userid/password cookies are stored (by this servlet, with a uri in the jsp's form like "/appname/ManualLogin"). The login.jsp page populates the form fields (${cookie.userid.value}) from the cookies with no problem. At logon, a user bean is stored. When the user goes to an internal page (like "http://host.com/UserData/userid/home.jsp"), if the user bean is not set, he will be redirected to an autologin servlet (from the jsp page, this is <jsp:forward page="/AutoLogin" />. This servlet attempts to get the userid/password cookies from the request. The autologin servlet does not see the cookies.
