Azure CDN adds x-microsoft headers to response, What are they and how to remove?

Placing any content into blob storage within a container hosted on Microsoft Azure set to public blob appends various x-ms-... headers in the HTTP response to a standard GET request from a browser. What are they used for, and can they be turned off? I dislike bloated and useless HTTP headers.

HTTP/1.1 200 OK
Content-Length: 1841396

I faced the same problem recently and I want to share information.

First, "x-ms-..." headers except "x-ms-meta-CbModifiedTime" is set by Azure Blob. I think Azure Blob, Azure CDN don't support the functions remove response headers now.

However, "x-ms-meta-{name}" headers return metadata set to each blob by not Microsoft but clients.

So who does create "CbModifiedTime" metadata?

I found CloudBerry Explorer ("Cb") set this metadata automatically. I couldn't found the way to be disable this function in Free Edition. If you care about response headers, you should consider to use other tools
