1005
1006Remove all cookies from the cookie jar that have been expired. If
1007C<$session_end> is given and true, then additionally remove all session
1008cookies.
1009
1010You should call this function (with a true C<$session_end>) before you
1011save cookies to disk, and you should call this function after loading them
1012again. If you have a long-running program you can additonally call this
1013function from time to time.
1014
1015A cookie jar is initially an empty hash-reference that is managed by this
1016module. It's format is subject to change, but currently it is like this:
1017
1018The key C<version> has to contain C<1>, otherwise the hash gets
1019emptied. All other keys are hostnames or IP addresses pointing to
1020hash-references. The key for these inner hash references is the
1021server path for which this cookie is meant, and the values are again
1022hash-references. The keys of those hash-references is the cookie name, and
1023the value, you guessed it, is another hash-reference, this time with the
1024key-value pairs from the cookie, except for C<expires> and C<max-age>,
1025which have been replaced by a C<_expires> key that contains the cookie
1026expiry timestamp.
1027
1028Here is an example of a cookie jar with a single cookie, so you have a
1029chance of understanding the above paragraph:
