That is the only way to know if the session is invalid..(or similarly u can do request.getSession(true) and check isNew on session)And yes for every request u have to do this...SO typically some where in your applications abstract action class U will have this as a preprocessing before the perform is called... >>4.From my understanding, I can set timeout in web.xml or use setMaxInactiveIterval(int ..). Usually which way should be use? I think the web.xml is better place as it becomes declarative instead of hardcoded.So just to check the time out, u dont need a next build. >>5. After user login, I want to forward the user to the page where he was when session timeout. Where should I save the information(with the information, I know where I should forward the user to)? I think one of teh ways to do this might be using cookies ..Check teh documentation for more details as i aslo dont know exactly how to do this.But u can use cookies to store user info.And in his case, as session is already timed out, i think this is the easiest way to save the information about the last action.. regards, Shirish -----Original Message----- From: hinbsls [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 17, 2002 3:27 PM To: struts-user Cc: hinbsls Subject: Struts and session Greetings: I am using struts1.1b2 to implement a web application. I have a question regarding to implementing session timeout. When session is invalidated, user who has logged in the system should be forwarded to login page. I am not clear about the followings, and hope someone can help me out. 1. Should I use request.getSession(false) to check if session is timeout? If so, that means for every request, it will check if session is invaildate. Will it cause performance problem? If not, which methods should I call to check it? 2. If I should use request.getSession(false) to check session timeout, where should I write the code? Should I write the code in every action class? 3. There are many methods related to session, such as getCreationTime, getLastAccessedTime,..Where and how should I use them in the implementation? 4.From my understanding, I can set timeout in web.xml or use setMaxInactiveIterval(int ..). Usually which way should be use? 5. After user login, I want to forward the user to the page where he was when session timeout. Where should I save the information(with the information, I know where I should forward the user to)? I searched the archive. However, it seems that I can't find the specific info.
