This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Our application authticates users using the basic authentication scheme. Since the user credentials are always part of the request header sent by the browser, how does one implement a 'logoff' ? Is there any way to invalidate a request header ?
Chen, If I remember this correctly, an authentication that was done through BASIC will be valid until the user closes her browser. If the authentication was done via a FORM, then you could simply call invalidate() on the HttpSession and the next fetch would require the user to login again. As always, you will definitely want to double-check this information--but I hope it gets you headed off in the right direction.
