|
* Local & Session storage
|
|
*
|
|
* Lifetimes in order from most persistent to most transient:
|
|
*
|
|
* + mc.account - synchronized with server account_data (requires auth)
|
|
* + mc.local - synchronized with window localStorage
|
|
* + mc.session - synchronized with window sessionStorage
|
|
* + mc.instance - not synchronized; lifetime is the same as mc object.
|
|
*
|
|
* Note that the storage objects are serialized to JSON when actually being stored.
|
|
* Anything placed inside a live storage object should have a JSON representation.
|
|
*
|
|
* Note that storage is partitioned based on the mc.opts.base_url. This ensures
|
|
* if the target server changes for whatever reason the webstorage objects will be
|
|
* different for different base URL's.
