| ** 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 |
