Answer: How can I delete a cookie?

See How can I maintain a session cookie for more information.

If you don't set an expiration date on a cookie that you've created, it will be deleted when the browser is closed.

If the user wants to delete a cookie created in a previous session, you can set the expiration date of the cookie in the past (or possibly set it to "", I haven't tried this).

If you'd like to learn more, you can read Netscape's Preliminary Specification for cookies.

Use "expires" or you can send the cookie again with a null value "";

Ex:

use CGI qw/:standard/; use CGI::Cookie; my %CookieVars = ( ISAUTH => $ActualCookieVars{ISAUTH}, USERNAME => $ActualCookieVars{USERNAME}, AUTHLEVEL => $ActualCookieVars{AUTHLEVEL}, MYNUMBER => "$mynumber" ); # set cookie to the user my $cookie1 = new CGI::Cookie( -name=>'Test', -value =>\%CookieVars, # var to be sent -expires=>'+1h', # time to expire -domain=>"teste.com", # domain -path=>'/', #option path -secure=>0 # no ssl );
