** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
37
** with input from Mike Belshe <mbelshe@netscape.com> and
38
** Michael Campanella <campanella@stevms.enet.dec.com>
39
** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
40
** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
41
** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
42
** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
43
** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
45
** - Increased version number - as some of the socket/error handling has
46
** fundamentally changed - and will give fundamentally different results
47
** in situations where a server is dropping requests. Therefore you can
48
** no longer compare results of AB as easily. Hence the inc of the version.
49
** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
50
** - Fixed proxy functionality, added median/mean statistics, added gnuplot
51
** output option, added _experimental/rudimentary_ SSL support. Added
52
** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
53
** - Fixed serious int overflow issues which would cause realistic (longer
54
** than a few minutes) run's to have wrong (but believable) results. Added
55
** trapping of connection errors which influenced measurements.
56
** Contributed by Sander Temme, Early 2001
58
** - Changed timeout behavour during write to work whilst the sockets
59
** are filling up and apr_write() does writes a few - but not all.
60
** This will potentially change results. <dirkx@webweaving.org>, April 2001
62
** Improvements to concurrent processing:
63
** - Enabled non-blocking connect()s.
64
** - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
65
** manage its entire set of socket descriptors).
66
** - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
67
** is now treated as fatal.
68
** Contributed by Aaron Bannert, April 24, 2002
71
** Internalized the version string - this string is part
72
** of the Agent: header and the result output.
75
** Adopted SSL code by Madhu Mathihalli <madhusudan_mathihalli@hp.com>
76
** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
77
** Introduces four 'if (int == value)' tests per non-ssl request.
80
** Switched to the new abstract pollset API, allowing ab to
81
** take advantage of future apr_pollset_t scalability improvements.

/* Note: this version string should start with \d+[\d\.]* and be a valid

87

88

89

90
