|
|
* The CSP implementation however does not allow http
|
|
* requests to succeed if executed in report-only mode.
|
|
* In such a case the CSP implementation reports the
|
|
* error back to the page.
|
|
*
|
|
* (2) MixedContent:
|
|
* The evalution of MixedContent whitelists all http
|
|
* requests with the promise that the http requests
|
|
* gets upgraded to https before any data is fetched
|
|
* from the network.
|
|
*
|
|
* (3) CORS:
|
|
* Does not consider the http request to be of a
|
|
* different origin in case the scheme is the only
|
|
* difference in otherwise matching URIs.
|
|
*
|
|
* (4) nsHttpChannel:
|
|
* Before connecting, the channel gets redirected
|
|
* to use https.
|
|
*
|
|
* (5) WebSocketChannel:
|
|
* Similar to the httpChannel, the websocketchannel
|
|
* gets upgraded from ws to wss.
