site security

<i><b>Originally posted by : chris mincarelli (cmincarelli@yahoo.com)</b></i><br />i've created a sign-in screen that compares a login to a table and allows access to the<br />site if the login matches. on a sucessful match i place a cookie with the info in it. the next the<br />user enters, i look for the cookie first, then the query string, and then fail.<br /><br />now i moved the site to frames, and the cookie is no longer visible to the application. what is<br />different about frames? if i enter the page without frames, it works!
