what about adding http range request support [1] to the backend? After I
comitted r8169 ("get only the last N bytes of a logfile") last week darix
suggested to use the http "Range" header instead of the "start" and "end"
query parameters. The advantage of using the range header is that it is
already part of the protocol and the range header isn't limited to the
"getlogfile()" function (we can use it whenever a file is replied).

Dunno, I don't see so many use cases. For the log file, I'd rather
have "give me the last 1000 lines" instead of bytes.

Yes, me too.

However, in general this is really great and important stuff. We should also
use it for logfile in the web client by default IMHO. Usually only last ~ 100
lines are interessting and I really hate to download > 10 MB of logfile just
for seeing the broken file list errors ;)

From an http perspective there is no such thing as "lines" - only
bytes. Using the range header instead of several parameters is, IMO, a
more elegant solution and puts the request at the proper layer. I'd
rather see Range headers used than yet-another
range-like-thing-that-isn't-ranges. In this case, I see it as a
correction. ;-)
