1006 | Remove all cookies from the cookie jar that have been expired. If |
|
|
1007 | C<$session_end> is given and true, then additionally remove all session |
|
|
1008 | cookies. |
|
|
1009 | |
|
|
1010 | You should call this function (with a true C<$session_end>) before you |
|
|
1011 | save cookies to disk, and you should call this function after loading them |
|

1012 | again. If you have a long-running program you can additonally call this |
|
|
1013 | function from time to time. |
|

1014 | |
|
|
1015 | A cookie jar is initially an empty hash-reference that is managed by this |
|
|
1016 | module. It's format is subject to change, but currently it is like this: |
|
|
1017 | |
|
|
1018 | The key C<version> has to contain C<1>, otherwise the hash gets |
|
|
1019 | emptied. All other keys are hostnames or IP addresses pointing to |
|
|
1020 | hash-references. The key for these inner hash references is the |
|
|
1021 | server path for which this cookie is meant, and the values are again |
|
|
1022 | hash-references. The keys of those hash-references is the cookie name, and |
|
|
1023 | the value, you guessed it, is another hash-reference, this time with the |
|
|
1024 | key-value pairs from the cookie, except for C<expires> and C<max-age>, |
|
|
1025 | which have been replaced by a C<_expires> key that contains the cookie |
|
|
1026 | expiry timestamp. |
|
|
