78 ** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
79 ** with input from Mike Belshe <mbelshe@netscape.com> and
80 ** Michael Campanella <campanella@stevms.enet.dec.com>
81 ** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
82 ** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
83 ** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
84 ** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
85 ** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
87 ** - Increased version number - as some of the socket/error handling has
88 ** fundamentally changed - and will give fundamentally different results
89 ** in situations where a server is dropping requests. Therefore you can
90 ** no longer compare results of AB as easily. Hence the inc of the version.
91 ** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
92 ** - Fixed proxy functionality, added median/mean statistics, added gnuplot
93 ** output option, added _experimental/rudimentary_ SSL support. Added
94 ** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
95 ** - Fixed serious int overflow issues which would cause realistic (longer
96 ** than a few minutes) run's to have wrong (but believable) results. Added
97 ** trapping of connection errors which influenced measurements.
98 ** Contributed by Sander Temme, Early 2001
100 ** - Changed timeout behavour during write to work whilst the sockets
101 ** are filling up and apr_write() does writes a few - but not all.
102 ** This will potentially change results. <dirkx@webweaving.org>, April 2001
103 ** Version 2.0.36-dev
104 ** Improvements to concurrent processing:
105 ** - Enabled non-blocking connect()s.
106 ** - Prevent blocking calls to apr_recv() (thereby allowing AB to
107 ** manage its entire set of socket descriptors).
108 ** - Any error returned from apr_recv() that is not EAGAIN or EOF
109 ** is now treated as fatal.
110 ** Contributed by Aaron Bannert, April 24, 2002
113 ** Internalized the version string - this string is part
114 ** of the Agent: header and the result output.
116 ** Version 2.0.37-dev
117 ** Adopted SSL code by Madhu Mathihalli <madhusudan_mathihalli@hp.com>
118 ** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
119 ** Introduces four 'if (int == value)' tests per non-ssl request.
122 /* Note: this version string should start with \d+[\d\.]* and be a valid
123 * string for an HTTP Agent: header when prefixed with 'ApacheBench/'.
124 * It should reflect the version of AB - and not that of the apache server
125 * it happens to accompany. And it should be updated or changed whenever
126 * the results are no longer fundamentally comparable to the results of
127 * a previous version of ab. Either due to a change in the logic of
128 * ab - or to due to a change in the distribution it is compiled with
129 * (such as an APR change in for example blocking).
131 #define AP_AB_BASEREVISION "2.0.40-dev"
137 * - has various other poor buffer attacks related to the lazy parsing of
138 * response headers from the server
139 * - doesn't implement much of HTTP/1.x, only accepts certain forms of
141 * - (performance problem) heavy use of strstr shows up top in profile
142 * only an issue for loopback usage
