[ftpext] draft-bryan-ftp-range-01 - reset

[Tatsuhiro Tsujikawa <[e-mail]>]

Hi,

draft-bryan-ftp-range-01 changed the way to reset the range command
previously issued.

4.  The RANGe Command (RANG)

  To reset the range command, "RANG 1 0" should be issued.  Invalid
   RANG requests where 'start-point' is larger than 'end-point'
   automatically reset the byte selection to the default, which is the
   whole file.

But currently, it states that server should respond with a 5yz reply
with "RANG 1 0".

4.3.  RANG Command Errors
   ...
   The server-PI SHOULD reply with a 5yz reply if the specified end
   point is larger than the actual file or the end point is before the
   start point.

I think "RANG 1 0" is a recommended way of reseting range, I think server must
reply with 200 reply. So I propose to add following sentence to the
above paragraph:

   But the server-PI MUST reply with a 200 reply if "RANG 1 0" is issued
   by client-PI because it is a valid way of reseting range.

Best regards,
