Chunk upload only first time run into Save function when the WebAPI disabled anonymous identity

Hi 

I am using the upload control, and fount some errors and I don't know how to fix it.

I am using chunk upload


add authorization before uploading, for runing into my api successfully.


The first time, it run into the save method, and I found the headers length is 14, contains "Authorization"


but the second time run the method , the headers length is 13 ? And when my WebAPI  disable anonymous identity, the second time doesn't run into the save mthod, only the first time run into save method. It seems lost the "Authorization"
