Probably wasn't done on the same page. Here's my guess at how these sites do that: (1) User visits login page, no cookie is set. (2) User enters username and password in the login page form, clicks the submit button, and the login page form posts back to itself. (3) The login page has logic at the top to check and see if the form has been posted...if so it verifies the user's credentials, sets a cookie, and then redirects to the first page of the application. (4) The first page of the application (main menu or whatever) checks to see if a cookie has been provided. If not, it displays the warning that the user has disabled cookies. So, the app sets the cookie and then immediately redirects to the page that checks the cookie. To the end user it would appear that the cookie was set and checked in the same page.
