Re: Cookie -> Delete -> Reset

If you delete and set the cookie on the same request the delete is completely redundant. It serves no purpose whatsoever because of the way cookies work and the way browsers accept them. If you do: setcookie('abc',1); setcookie('abc',2); This causes PHP to these headers: Set-Cookie: abc=1 Set-Cookie: abc=2 The browser will only accept the second one. However, in general there is nothing wrong with what you are doing. Turn on your cookie warnings in your browser or telnet to port 80 on your web server and watch the raw cookies sent by your PHP script. Make sure they look the way you expect them to. -Rasmus On Tue, 9 Jan 2001, Abe Asghar wrote: > That makes sense Rasmus, but the reason I delete and reset the cookie is > because I am trying to measure activity and not just a set time.
