a210c2e5add831cd438183c8602ed8e610922beaSimon Ulbricht ** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
a210c2e5add831cd438183c8602ed8e610922beaSimon Ulbricht ** with input from Mike Belshe <mbelshe@netscape.com> and
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** Michael Campanella <campanella@stevms.enet.dec.com>
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** Version 1.3d
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - Increased version number - as some of the socket/error handling has
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** fundamentally changed - and will give fundamentally different results
abea93ed557b22ea833e1524ee5ca11afc12208aSimon Ulbricht ** in situations where a server is dropping requests. Therefore you can
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** no longer compare results of AB as easily. Hence the inc of the version.
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
9da6e0cb2ea6e43f5b09dcd2a9af5468a5d0fcf4Christian Maeder ** - Fixed proxy functionality, added median/mean statistics, added gnuplot
369771f5d48a40eda134026b1f45f63b2c00bdb8Simon Ulbricht ** output option, added _experimental/rudimentary_ SSL support. Added
6150196e8d99f7161a622fdc1a872fecd378195fSimon Ulbricht ** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
369771f5d48a40eda134026b1f45f63b2c00bdb8Simon Ulbricht ** - Fixed serious int overflow issues which would cause realistic (longer
369771f5d48a40eda134026b1f45f63b2c00bdb8Simon Ulbricht ** than a few minutes) run's to have wrong (but believable) results. Added
65660c22133e6de16f9ece7b36ac6423014b20aaChristian Maeder ** trapping of connection errors which influenced measurements.

65660c22133e6de16f9ece7b36ac6423014b20aaChristian Maeder ** Version 1.3e
65660c22133e6de16f9ece7b36ac6423014b20aaChristian Maeder ** - Changed timeout behavour during write to work whilst the sockets
1651c7f5055453e18a8c34f96c333e2aa702a34eSimon Ulbricht ** are filling up and apr_write() does writes a few - but not all.
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** This will potentially change results. <dirkx@webweaving.org>, April 2001
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** Version 2.0.36-dev
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** Improvements to concurrent processing:
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** - Enabled non-blocking connect()s.
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** manage its entire set of socket descriptors).
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** is now treated as fatal.

e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** Internalized the version string - this string is part

65660c22133e6de16f9ece7b36ac6423014b20aaChristian Maeder ** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
d8623e217fff016f9e1759b5603fc06b29fda62cChristian Maeder ** Introduces four 'if (int == value)' tests per non-ssl request.

e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** Switched to the new abstract pollset API, allowing ab to
e9a1a4d5820d527a6800d524ebaf29fbad6196c6Simon Ulbricht ** take advantage of future apr_pollset_t scalability improvements.
