content-type incorrectly set in Win8.1+IE11 for pdf/pptx

[stevesap]

Using Windows 8 + IE11 and multipart=false, the content-type request header is being set to application/octet-stream rather than the real mime type in case of pdf and pptx (and possibly other types) whereas in other browsers, the content-type is being set correctly (for example, application/pdf in case of pdf).

Thanks for the info, I'll mark this as browser bug.

Thanks. Is there any workaround or does this mean the issue cannot be resolved until it's fixed in IE11? Do you guys communicate browser bugs to the IE11 team?

Correction: The issue was reproduced on Windows 8.1, not Windows 8. I did not try it in Windows 8. In Windows 7 with IE11, the issue is not reproducible.

Judging from your error report, I don't see a feasible workaround at the moment.
If I can, I report all browser bugs I encounter, however since you discovered it and can reproduce it, you're the best person to do this. ;)
