* Protocol used to relay chrome observer notifications related to clearing data
|
|
* to SessionStorageManager instances in content processes. A single instance is
|
|
* created by each content process when LocalStorage NextGen is enabled. When
|
|
* LSNG is disabled, the notifications are instead propagated via
|
|
* PBackgroundStorageChild. This does mean there are potentially slight ordering
|
|
* differences in when the notification will be received and processed. It's
|
|
* okay for this protocol to be managed by PContent rather than PBackground
|
|
* because these notifications are both rare and to-child-only. (Legacy
|
|
* LocalStorage was moved to PBackground from PContent because of parent-process
|
|
* main-thread contention for the processing of "parent:" messages in a very
|
|
* performance-sensitive context!)
