451 Unavailable For Legal Reasons



I do not know that is this dangerous, but someone seems
already use 451 code.


3.1.5.2.2 HTTP Error 451
https://msdn.microsoft.com/en-us/library/gg651019


Perhaps someone may misclassify ActiveSync redirection
as "Unavailable For Legal Reasons".

Seems that ActiveSync can not misclassify
"Unavailable For Legal Reasons" as redirection
bacause it needs X-MS-Location: header field.

I noticed that from Wikipedia.

This is most likely not serius problem. And 451 is not
listed on 

https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml

so this is mostly Microsoft's problem.
