If the cookie does not have an expiration date, it is a session cookie and will be removed when the browser closes. Otherwise, set the expiration date of the cookie to a date in the past and re-send it to the browser. See CGI::Cookie, in particular here.	[reply]

If you're using CGI.pm, which is a good idea to use when writing perl/cgi scripts, you can take advantage of it's built in cookie support. The relevant section in the documentation states that "Negative expiration times (e.g. "-1d") cause some browsers to delete the cookie from its persistent store. This is a poorly documented feature.". Here's some sample code to help you delete a cookie: `my $cookie = $query->cookie ( -name => 'foo', -value => 'bar', -expires => '-1d', -path => '/', -domain => 'my.domain.com' ); print $query->header(-cookie=>$cookie);` [download] - wil	[reply] [d/l]

As alternative to setting expire time to a date in the past you can just supply empty value for the cookie. Most browsers seems to delete cookie with empty value. -- Ilya Martynov (http://martynov.org/)	[reply]

When you create the cookie if you set the expires option to blank or undefined the cookie will be deleted once the browser empties its cache( ex: when it exits)thats about the only way i know how to delete a cookie using perl "Your baudrate depends on the size of your pipe". -ALex Simonelis	[reply]
