This problem does not occur with IIS 6 on an earlier server operating system. Only with IIS 10 on Windows Server 2016.

We are experiencing this too. We have IIS 10 and ColdFusion 2016. Any solutions?
This is apparently a bug in Safari version 9 and newer. Affects ColdFusion running on Windows Server 2016, but also other applications (reported by other developers of ASP, ASP.net and NGINX.)
Temporary fix (disable http2 on Windows Server 2016 in the registry):
- Open the registry editor (regedit)
- Browse to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters
- Enter 2 new DWORD Values EnableHttp2Cleartext and EnableHttp2Tls
- Set their values to 0
I believe this was resolved with iOS 11. We had this issue but after upgrading to iOS 11, I could no longer reproduce this issue.
