hmm... I don't think you'd want to inject an extra one second delay into every
request.
Perhaps the flow could go a bit like this, so the client doesn't send more than
one request without getting any trailing bytes:
(C=client, S=server, line numbers and byte counts are arbitrary)
C:request:/progressiveHtml
S: get lines 1-5, bytes:100
C: wait 5 seconds
C: request:/progressiveHtml, start=100
S: get lines 6-7, omit part of line 8, bytes:+30 more bytes up to end of line
7, flag to indicate partial response
C: wait 5 seconds
C: request:/progressiveHtml, start=130, partialLine=yes
S: get line 8-10, omit part of line 11,
ignore partialLine option since there's at least one newline,
bytes:+40 more to end of line 10,
flag to indicate partial response
C:wait 5 seconds
C: request:/progressiveHtml, start=170, partialLine=yes
S: get rest of line 11, include all bytes
bytes:+2 more
flag to indicate partial response (b/c no newline)
C:wait 5 seconds
C: request:/progressiveHtml, start=172, partialLine=yes
S: get rest of line 11, line 12, end of data is a newline so partialLine=no,
bytes:+20 more
C: wait 5 seconds
C: request:/progressiveHtml, start=192, partialLine=no
