            Bug ID: 160890
           Summary: Following redirects to non-punycoded domains
    Classification: Unclassified
           Product: WebKit
           Version: Safari 9
          Hardware: All
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ruslan.kudubayev at gmail.com

Latest Safari both on iPhone and Mac seem to have an issue with following redirects to urls where the domain is non-punycoded (i.e. using international characters). When same url is pasted into the address bar the dns resolves correctly.

To reproduce, you'd generally need a redirector - it's hard to find one that wouldn't automatically punycode the urls.
I've created a 302 redirect on a cloud machine (redirects to russian domain кто.рф). This does not work on iPhone's Safari and Chrome (works in Google Search App). Works fine on my desktop machine (unix, chrome) and using wget command. On Mac, it doesn't work on Safari, but works in Chrome. So seems like a webkit issue.

Test url: http://104.197.144.181/punycodetest.php - I'll take this down in a few days.
