Tomcat creates sessions when you need one. If you are swithing server names, then your browser is not submitting the cookie that is likely to be used for session tracking. If you were using URL rewriting instead of cookies, my guess is that you never would have known that there was a problem. > So when we called the servlet initially using, > for example, http://123.123.123.123/servlet and loaded the session > data, a subsequent call to http://hostname/servlet created a new > session - hence the appearance of sessions going out of sync. Yup. Your browser stopped sending the cookie (because of the hostname change) and so you "lost" your session. On the bright side, you got yourself a new one! > Now we've standardised and everything is working as expected. That's always best. I hope you mean that the application itself has been standardized, instead of the method of access. > Is this a known behaviour or is there something we can do through > config to get around this problem? Tomcat doesn't mess with your URLs. If you emit a URL to your client browser with the address 123.123.123.123, then that's what the client is going to get. On the other hand, if you let your content delivery tools (JSP taglibs or something similar) do the work of emitting URLs for you, you should never have to worry about this kind of thing. Those tools are written so that they either emit relative URLs (which have no hostname information in them, so there's no confusion), or they emit fully-qualified URLs containing the hostname that is currently being used to access the webapp, which should therefore never change. I wouldn't recommend hard-coding the hostname anywhere in your webapp. You never know when you are going to have to re-deploy the app into a separate environment. If you have hard-coded the hostname, then you'll have to go back into the code and recompile in order to re-deploy. I hope that clears things up, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFnmK/9CaO5/Lv0PARAgGAAKDD2u0ECd0IZfT7Zl6PBP2t9QxYZwCfSf1r tC4C6BVXVJ1vlVJcXh5CGbE= =3r+A -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
