1003=item AnyEvent::HTTP::cookie_jar_expire $jar[, $session_end]
1004
1005Remove all cookies from the cookie jar that have been expired. If
1006C<$session_end> is given and true, then additionally remove all session
1007cookies.
1008
1009You should call this function (with a true C<$session_end>) before you
1010save cookies to disk, and you should call this function after loading them
1011again. If you have a long-running program you can additonally call this
1012function from time to time.
1013
1014A cookie jar is initially an empty hash-reference that is managed by this
1015module. It's format is subject to change, but currently it is like this:
1016
1017The key C<version> has to contain C<1>, otherwise the hash gets
1018emptied. All other keys are hostnames or IP addresses pointing to
1019hash-references. The key for these inner hash references is the
1020server path for which this cookie is meant, and the values are again
1021hash-references. The keys of those hash-references is the cookie name, and
1022the value, you guessed it, is another hash-reference, this time with the
1023key-value pairs from the cookie, except for C<expires> and C<max-age>,
1024which have been replaced by a C<_expires> key that contains the cookie
1025expiry timestamp.
1026
1027Here is an example of a cookie jar with a single cookie, so you have a
1028chance of understanding the above paragraph:
