f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** with input from Mike Belshe <mbelshe@netscape.com> and
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** Michael Campanella <campanella@stevms.enet.dec.com>
2d2eda71267231c2526be701fe655db125852c1ffielding ** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** Version 1.3d
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - Increased version number - as some of the socket/error handling has
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** fundamentally changed - and will give fundamentally different results
2d2eda71267231c2526be701fe655db125852c1ffielding ** in situations where a server is dropping requests. Therefore you can
2d2eda71267231c2526be701fe655db125852c1ffielding ** no longer compare results of AB as easily. Hence the inc of the version.
2d2eda71267231c2526be701fe655db125852c1ffielding ** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** - Fixed proxy functionality, added median/mean statistics, added gnuplot
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** output option, added _experimental/rudimentary_ SSL support. Added
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
2d2eda71267231c2526be701fe655db125852c1ffielding ** - Fixed serious int overflow issues which would cause realistic (longer
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** than a few minutes) run's to have wrong (but believable) results. Added
f062ed7bd262a37a909dd77ce5fc23b446818823fielding ** trapping of connection errors which influenced measurements.

2d2eda71267231c2526be701fe655db125852c1ffielding ** Version 1.3e
2d2eda71267231c2526be701fe655db125852c1ffielding ** - Changed timeout behavour during write to work whilst the sockets
2d2eda71267231c2526be701fe655db125852c1ffielding ** are filling up and apr_write() does writes a few - but not all.
2d2eda71267231c2526be701fe655db125852c1ffielding ** This will potentially change results. <dirkx@webweaving.org>, April 2001
2d2eda71267231c2526be701fe655db125852c1ffielding ** Version 2.0.36-dev
fcc25eda7b150e226d3c1cdaea66a943d3fdee4erbb ** Improvements to concurrent processing:
b980ad7fdc218b4855cde9f75a747527f50c554dwrowe ** - Enabled non-blocking connect()s.
ab5581cc78e9d865b0a6ab1404c53347b3276968rbb ** - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
92f3af936ce61f25358a3ee4f28df2f6d62040dfdreid ** manage its entire set of socket descriptors).
fcc25eda7b150e226d3c1cdaea66a943d3fdee4erbb ** - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
c9a95767fbf0f5fb0976a06b97a256033925e433rbb ** is now treated as fatal.
