OK, thanks for your response.
My main problem is now solved. I want just two little add-on : - Is it possible to force Tomcat to delete de SESSION.ser (or all the work dir) on shutdown ? - I f I understand the session, Tomcat try firts to work with Cookie and then if, cookie are deactivated, Tomcat use url rewriting. I tried to see the Cookie générated by tomcat on my brower (IE5.5) but i can't. Is it a memory cookie or is it in the file system (on win2k, c:/documents and settings/$user$/Cookie ??) ------------------------------ A++ Stéphane -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
