I have problem with submitting login form dynamically, the response text always been the same as the previous submission. Such as if user enter the wrong password for the first time, the server will response text of wrong password, but if the user has enter the correct password for the second time, but the server still response the wrong password text. I am using firefox 2.0 I have even try to append the url with 'sid='+ Math.random() but it does not work too. Any idea why ?
