Safari could not get xod file with range-request

[Richard]

Hi all,

Now I have an issus about Safari couldn't get xod files with range-request(Invalid XOD file: Zip end header data is wrong size!)!!  But we can get xod files through  IE, Chrome, Firefox. They were fine. Could you please help me to fix this issus?

The website host in IIS 8.0. Here are some code in my back-end.

                    response.Headers.Add("Accept-Ranges", "*");

                    response.Headers.Add("Content-Range", contentRange);
                    response.Headers.Add("Access-Control-Max-Age","3000");
                    response.Headers.Remove("Cache-Control");
                    response.Headers.Add("Access-Control-Allow-Origin", "*");
                    response.Headers.Add("Access-Control-Allow-Credentials", "true");
                    response.Headers.Add("Access-Control-Allow-Headers", "origin,range,x-requested-with");
                    response.Headers.Add("Access-Control-Allow-Methods", "GET");

Hoping for your reply!

Regards,
Richard
