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1025 | which have been replaced by a C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. |
