The `topPrivatelyControlledDomain()` function seems to be platform specific as it depends on libraries such as libpsl. It is implemented by the soup and curl platforms but will also be needed on Apple/win ports.

That is what the Fetch spec recommends and other engines like Chromium do. It is slightly error prone since Requests seem to be re-created often and it is possible to incorrectly `setURL()`.

This is probably a bug. So we can simply change `topPrivatelyControlledDomain()` to return `localhost` for `*.localhost` and it fixes these tests. I can't change the macOS impl of this though and its probably a change worth discussing if it makes sense.

Otherwise, we can check for same site/same origin. I don't think we have enough information as-is. What we need to defend against is a redirect chain such as: http://origin1 (site=undefined) -> http://origin2 (site=undefined) -> https://origin2 (site=cross-origin) When we get to https://origin2 we need the full chain to know the correct value, otherwise its easy to mistakenly call it same-origin. My comment above mentions the idea of tracking the list with all Requests.

It might be easy but we do not need the whole chain, since the last computed value is correct for all the previous redirects. We just need to take into account the last value and the new URL. We do this to compute whether a request is cross origin or not (once it is cross origin, it stays cross origin).

Otherwise, we > can check for same site/same origin. I've implemented this where it's tracked for every request in the chain. One thing I could use help with is that `www.localhost` requests are blocked, even though it should be considered same-site. I fixed the `www.127.0.0.1` ones failing upstream: https://github.com/web-platform-tests/wpt/pull/33484

From what I could tell these both compare domains the same and both use topPrivatelyControlledDomain(). However when PSL isn't available RegistrableDomain falls back to full host comparisons. I think a hard requirement on PSL for this feature is a good idea.

FetchOptions should more or less remain immutable during a load. FetchOptions values are set by the creator of the load to properly setup the load.

Maybe I'm missing it. But `CachedResourceLoader::updateHTTPRequestHeaders()` doesn't seem to have easy access to a SubResourceLoader to get this information? `CachedResourceLoader::requestResource()` updates the request headers first, then creates a `CachedResource` with that information but we can't get the SubresourceLoader until after that?

CachedResourceLoader::updateHTTPRequestHeaders() is called for the initial load. We can compute the value from the request itself. SubresourceLoader will compute this same value as well (we can use the same routine as a free function) and in case of redirection will update this value to a new value. SubresourceLoader can pass this new value to updateRequestAfterRedirection. This way, we keep the model of FetchOptions being 'immutable' load options set by the client, and this site property being an internal state of the loader.

Can we fix it? I will look into this in a bit more detail why these are NOTRUN rather than FAIL. Some failures are expected for the same domain issue.
(In reply to Patrick Griffis from comment #26) > I will look into this in a bit more detail why these are NOTRUN I can at least confirm these are genuinely NOTRUN and they were not ran before this patch. All of the test cases appendChild() an element (be it a link, or embed, etc) and WebKit never loads the elements. The only one that WebKit loads is the link element with `rel=preload` set.

It seems to me that we *could* set up our tests so they see a fake domain without system-wide changes as root. These might require platform-specific techniques so the way we do this with CFNetwork on macOS and iOS might not be the same as on other platforms. I’m not saying we need to do this immediately, or that it is required for this patch, but I would like to know more about whether we plan to deal with this long term or not. Is there someone else watching this bug who knows about this?

On libsoup we can make a custom GResolver to fake DNS responses and CURL does allow hardcoding an IP to a hostname. They are all very platform specific.
