Hello!
Thank you to all for your hints. Now, I want to tell you, what I did at last. My application consists of nearly 100% forms. The application is logically devided into two parts (-> represented by two browser windows), and it must be possible to get from one part to the other. If somebody goes to the other part, datas must be migrated from the first one, which needn't to be closed - it's possible, that the user works with both parts at the same time. To achieve these needs, I created an object in the ServletContext, where datas are stored, which are needed to migrate from one session to another session. The key to these data in this object is the session ID. If an user switches to another part of the application, this is done using a direct call to a jsp, like href=some.jsp;sessionid=E19593A3AB3BB4EBB92C6E64916B729C I'm using sessionid (and not jsessionid), because this way, the request is sessionless (I'm using URL-rewriting for session-tracking and https) and I can check in the loginfilter myself, if the request belongs to an already logged in user. If the sessionid is valid, the user gets a new one and I can fetch data from the ServletContext-object.
