If a client tries to "restart in the middle", meaning that it asks for a
byte range, then -
- The server must be AOLserver 3.2+ad12 or 3.3+ad13 (if it's AOLserver
at all) for the byte range request to be honored (assuming it's handled
by fastpath or ns_returnfile). Other versions of AOLserver will simply
return the whole document.
- The client ought to provide either an If-Range header or an
If-Unmodified-Since header to be safe, but it's not required to.
- If the client provides an If-Range header, then AOLserver will return
either the requested range (if the file date matches the If-Range date)
or the whole file (if the date doesn't match).
- If the client provides an If-Unmodified-Since header, then AOLserver
will return either the requested range (if the file date matches the
If-Unmodified-Since header) or a 412 Precondition Failed error (if the
date doesn't match).
