* Returns true if the "HTTPS state" of the document should be "modern". See:

*
|
|
* https://html.spec.whatwg.org/#concept-document-https-state
|
|
* https://fetch.spec.whatwg.org/#concept-response-https-state
|
|
*
|
|
* Note: this function only relates to figuring out HTTPS state, which is an
|
|
* input to the Secure Context algorithm. We are not actually implementing any
|
|
* part of the Secure Context algorithm itself here.
|
|
*
|
|
* This is a bit of a hack. Ideally we'd propagate HTTPS state through
|
|
* nsIChannel as described in the Fetch and HTML specs, but making channels
|
|
* know about whether they should inherit HTTPS state, propagating information
|
|
* about who the channel's "client" is, exposing GetHttpsState API on channels
|
|
* and modifying the various cache implementations to store and retrieve HTTPS
|
|
* state involves a huge amount of code (see bug 1220687). We avoid that for
|
|
* now using this function.
|
|
*
|
|
* This function takes advantage of the observation that we can return true if
|
|
* nsIContentSecurityManager::IsOriginPotentiallyTrustworthy returns true for
|
|
* the document's origin (e.g. the origin has a scheme of 'https' or host
|
|
* 'localhost' etc.). Since we generally propagate a creator document's origin
|
|
* onto data:, blob:, etc. documents, this works for them too.
|
|
*
|
|
* The scenario where this observation breaks down is sandboxing without the
|
|
* 'allow-same-origin' flag, since in this case a document is given a unique
|
|
* origin (IsOriginPotentiallyTrustworthy would return false). We handle that
|
|
* by using the origin that the document would have had had it not been
|
|
* sandboxed.
|
|
*
|
|
* DEFICIENCIES: Note that this function uses nsIScriptSecurityManager's
|
|
* getChannelResultPrincipalIfNotSandboxed, and that method's ignoring of
|
|
* sandboxing is limited to the immediate sandbox. In the case that aDocument
|
|
* should inherit its origin (e.g. data: URI) but its parent has ended up
|
|
* with a unique origin due to sandboxing further up the parent chain we may
|
|
* end up returning false when we would ideally return true (since we will
|
|
* examine the parent's origin for 'https' and not finding it.) This means
|
|
* that we may restrict the privileges of some pages unnecessarily in this
|
|
* edge case.
