So, to clarify:
- The user is browsing around in a WKWebView app.
- The user clicks on a link that the app would like to download instead of display in the WKWebView.
- The app denies the load in the policy handler, and then attempts to load the URL using an NSURLSessionDownloadTask inside the app process.
- That fails when the URL is protected by some sort of auth (cookie, http auth, ntlm, etc)
If my recounting of the above scenario is correct, then the reason it fails is because the browsing session (including cookies, credentials, etc) is held by the networking process, but since the app is trying the load inside the app process, the download doesn't go through.
Is my understanding correct?</pre>
