/*
** 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 - <sctemme@covalent.net>, Early 2001
** Version 1.3e
** - Changed timeout behavour 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
**

/*
* BUGS:
*
* - uses strcpy/etc.
* - has various other poor buffer attacks related to the lazy parsing of
* response headers from the server
* - 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
* only an issue for loopback usage
