|
|
* integrity metadata
|
|
* The integrity metadata used for the initial fetch. This is
|
|
* implemented in ScriptLoadRequest, as it changes for every

* ScriptLoadRequest.
|
|
*
|
|
* referrerPolicy
|
|
* For a module script, its referrerPolicy will be updated if there is a
|
|
* HTTP Response 'REFERRER-POLICY' header, given this value may be different
|
|
* for every ScriptLoadRequest, so we store it directly in
|
|
* ScriptLoadRequest.

* In the case of classic scripts without dynamic import, this object is

* used once. For modules, this object is propogated throughout the module

|
* tree. If there is a dynamically imported module in any type of script,
|
|
* the ScriptFetchOptions object will be propogated from its importer.
