/*
** HISTORY:
** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
** with input from Mike Belshe <mbelshe@netscape.com> and
** Michael Campanella <campanella@stevms.enet.dec.com>
** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
** Version 1.3d
** - Increased version number - as some of the socket/error handling has
** fundamentally changed - and will give fundamentally different results
** in situations where a server is dropping requests. Therefore you can
** no longer compare results of AB as easily. Hence the inc of the version.
** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
** - Fixed proxy functionality, added median/mean statistics, added gnuplot
** output option, added _experimental/rudimentary_ SSL support. Added
** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
** - Fixed serious int overflow issues which would cause realistic (longer
** than a few minutes) run's to have wrong (but believable) results. Added
** trapping of connection errors which influenced measurements.
** Contributed by Sander Temme, Early 2001
** Version 1.3e
** - Changed timeout behavior during write to work whilst the sockets
** are filling up and apr_write() does writes a few - but not all.
** This will potentially change results. <dirkx@webweaving.org>, April 2001
** Version 2.0.36-dev
** Improvements to concurrent processing:
** - Enabled non-blocking connect()s.
** - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
** manage its entire set of socket descriptors).
** - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
** is now treated as fatal.
** Contributed by Aaron Bannert, April 24, 2002
**
** Version 2.0.36-2
** Internalized the version string - this string is part
** of the Agent: header and the result output.
**
** Version 2.0.37-dev
** Adopted SSL code by Madhu Mathihalli <madhusudan_mathihalli@hp.com>
** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
** Introduces four 'if (int == value)' tests per non-ssl request.
**
** Version 2.0.40-dev
** Switched to the new abstract pollset API, allowing ab to
** take advantage of future apr_pollset_t scalability improvements.
** Contributed by Brian Pane, August 31, 2002
**
** Version 2.3
** SIGINT now triggers output_results().
** Contributed by colm, March 30, 2006

/* Note: this version string should start with \d+[\d\.]* and be a valid
* string for an HTTP Agent: header when prefixed with 'ApacheBench/'.
* It should reflect the version of AB - and not that of the apache server
* it happens to accompany. And it should be updated or changed whenever
* the results are no longer fundamentally comparable to the results of
* a previous version of ab. Either due to a change in the logic of
* ab - or to due to a change in the distribution it is compiled with
* (such as an APR change in for example blocking).

* BUGS:

* - doesn't implement much of HTTP/1.x, only accepts certain forms of
* responses
* - (performance problem) heavy use of strstr shows up top in profile
