// Define an enumeration to reflect the concept of response tainting from the
|
|
// the fetch spec:
|
|
//
|
|
// https://fetch.spec.whatwg.org/#concept-request-response-tainting
|
|
//
|
|
// Roughly the tainting means:
|
|
//
|
|
// * Basic: the request resulted in a same-origin or non-http load
|
|
// * CORS: the request resulted in a cross-origin load with CORS headers
|
|
// * Opaque: the request resulted in a cross-origin load without CORS headers
|
|
//
|
|
// The enumeration is purposefully designed such that more restrictive tainting
|
|
// corresponds to a higher integral value.
|
|
//
|
|
// NOTE: Checking the tainting is not currently adequate. You *must* still
|
|
// check the final URL and CORS mode on the channel.
|
|
//
|
|
// These values are currently only set on the channel LoadInfo when the request
|
|
// was initiated through fetch() or when a service worker interception occurs.
|
|
// In the future we should set the tainting value within necko so that it is
|
|
// consistently applied. Once that is done consumers can replace checks against
|
|
// the final URL and CORS mode with checks against tainting.
