Incidentally, I just checked on the idea of the "comma" being a header

I found this implementation by Microsoft of a Content-Range with a
different unit range:
It uses the comma to separate multiple ranges.

Also, I checked the HTTP specification and wasn't able to find
anywhere that the comma is indeed used for such header separation.

According to http://www.cs.columbia.edu/sip/syntax/rfc2068.html the
characters in tspecials are explicitly allowed as field-content.

Yves, can you provide a link to where that use of comma in HTTP header
fields is forbidden?
