* if a cookie is used in insert+indirect mode, it's desirable that the
the servers don't see it. It was not possible to remove it correctly
with regexps, so now it's removed automatically.
* don't use snprintf()'s return value as an end of message since it may
be larger. This caused bus errors and segfaults in internal libc's
getenv() during localtime() in send_log().
* removed dead insecure send_syslog() function and all references to it.
* fixed warnings on Solaris due to buggy implementation of isXXXX().
* option "dontlognull"
* fixed "double space" bug in config parser
* fixed an uninitialized server field in case of dispatch
with no existing server which could cause a segfault during
logging.
* the pid logged was always the father's, which was wrong for daemons.
* fixed wrong level "LOG_INFO" for message "proxy started".
* http logging is now complete :
- ip:port, date, proxy, server
- req_time, conn_time, hdr_time, tot_time
- status, size, request
* source address binding
* regex are now chained and not limited anymore.
* unavailable server now returns HTTP/502.
* increased per-line args limit to 40
* added reqallow/reqdeny to block some request on matches
* added HTTP 400/403 responses
* added a 'NOTES' file
* connection logging displayed incorrect source address.
* added proxy start/stop and server up/down log events.
* replaced log message short buffers with larger trash.
* enlarged buffer to 8 kB and replace buffer to 4 kB.
* added a config.rc example for Formilux
* added a build script for Formilux
* fixed a bug in buffer management where we could have a loop
between event_read() and process_{cli|srv} if R==BUFSIZE-MAXREWRITE.
=> implemented an adjustable buffer limit.
* fixed a bug : expiration of tasks in wait queue timeout is used again,
and running tasks are skipped.
* added some debug lines for accept events.
* send warnings for servers up/down.
* added OpenBSD, Linux-2.2 and Linux-2.4 targets to the Makefile
* added a Formilux init script
* fixed a few timeout bugs
* rearranged the task scheduler subsystem to improve performance,
add new tasks, and make it easier to later port to librt ;
* allow multiple accept() for one select() wake up ;
* implemented internal load balancing with basic health-check ;
* cookie insertion and header add/replace/delete, with better strings
support.
* reworked buffer handling to fix a few rewrite bugs, and
improve overall performance.
* implement the "purge" option to delete server cookies in direct mode.
* fixed some error cases where the maxfd was not decreased.
* now supports transparent proxying, at least on linux 2.4.
* soft stop works again (fixed select timeout computation).
* it seems that TCP proxies sometimes cannot timeout.
* added a "quiet" mode.
* enforce file descriptor limitation on socket() and accept().
