|
|
This wpt should run on an origin different from https://www1.web-platform.test:8444/,
|
|
from where cross-orign WebBundles are served.
|
|
|
|
This test uses a cross-origin WebBundle,
|
|
https://www1.web-platform.test:8444/web-bundle/resources/wbn/cors/corp.wbn,
|
|
which is served with an Access-Control-Allow-Origin response header.
|
|
|
|
`corp.wbn` includes three subresources:
|
|
a. `no-corp.js`, which doesn't include a Cross-Origin-Resource-Policy response header.
|
|
b. `corp-same-origin.js`, which includes a Cross-Origin-Resource-Policy: same-origin response header.
|
|
c. `corp-cross-origin.js`, which includes a Cross-Origin-Resource-Policy: cross-origin response header.
