* ChangeLog :
|
|
*
|
|
* 2002/10/18 : 1.1.17
|
|
* - add the notion of "backup" servers, which are used only when all other
|
|
* servers are down.
|
|
* - make Set-Cookie return "" instead of "(null)" when the server has no
|
|
* cookie assigned (useful for backup servers).
|
|
* - "log" now supports an optionnal level name (info, notice, err ...) above
|
|
* which nothing is sent.
|
|
* - replaced some strncmp() with memcmp() for better efficiency.
|
|
* - added "capture cookie" option which logs client and/or server cookies
|
|
* - cleaned up/down messages and dump servers states upon SIGHUP
|
|
* - added a redirection feature for errors : "errorloc <errnum> <url>"
|
|
* - now we won't insist on connecting to a dead server, even with a cookie,
|
|
* unless option "persist" is specified.
|
|
* - added HTTP/408 response for client request time-out and HTTP/50[234] for
|
|
* server reply time-out or errors.
|
|
* 2002/09/01 : 1.1.16
|
|
* - implement HTTP health checks when option "httpchk" is specified.
|
|
* 2002/08/07 : 1.1.15
|
|
* - replaced setpgid()/setpgrp() with setsid() for better portability, because
|
|
* setpgrp() doesn't have the same meaning under Solaris, Linux, and OpenBSD.
|
|
* 2002/07/20 : 1.1.14
|
|
* - added "postonly" cookie mode
|
|
* 2002/07/15 : 1.1.13
|
|
* - tv_diff used inverted parameters which led to negative times !
|
|
* 2002/07/13 : 1.1.12
|
|
* - fixed stats monitoring, and optimized some tv_* for most common cases.
|
|
* - replaced temporary 'newhdr' with 'trash' to reduce stack size
|
|
* - made HTTP errors more HTML-fiendly.
|
|
* - renamed strlcpy() to strlcpy2() because of a slightly difference between
|
|
* their behaviour (return value), to avoid confusion.
|
|
* - restricted HTTP messages to HTTP proxies only
|
|
* - added a 502 message when the connection has been refused by the server,
|
|
* to prevent clients from believing this is a zero-byte HTTP 0.9 reply.
|
|
* - changed 'Cache-control:' from 'no-cache="set-cookie"' to 'private' when
|
|
* inserting a cookie, because some caches (apache) don't understand it.
|
|
* - fixed processing of server headers when client is in SHUTR state
|
|
* 2002/07/04 :
|
|
* - automatically close fd's 0,1 and 2 when going daemon ; setpgrp() after
|
|
* setpgid()
|
|
* 2002/06/04 : 1.1.11
|
|
* - fixed multi-cookie handling in client request to allow clean deletion
|
|
* in insert+indirect mode. Now, only the server cookie is deleted and not
|
|
* all the header. Should now be compliant to RFC2109.
|
|
* - added a "nocache" option to "cookie" to specify that we explicitly want
|
|
* to add a "cache-control" header when we add a cookie.
|
|
* It is also possible to add an "Expires: <old-date>" to keep compatibility
|
|
* with old/broken caches.
|
|
* 2002/05/10 : 1.1.10
|
|
* - 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.
|
|
* 2002/04/19 : 1.1.9
|
|
* - 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().
|
|
* 2002/04/18 : 1.1.8
|
|
* - 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".
|
|
* 2002/04/13 :
|
|
* - http logging is now complete :
|
|
* - ip:port, date, proxy, server
|
|
* - req_time, conn_time, hdr_time, tot_time
|
|
* - status, size, request
|
|
* - source address
|
|
* 2002/04/12 : 1.1.7
|
|
* - added option forwardfor
|
|
* - added reqirep, reqidel, reqiallow, reqideny, rspirep, rspidel
|
|
* - added "log global" in "listen" section.
|
|
* 2002/04/09 :
|
|
* - added a new "global" section :
|
|
* - logs
|
|
* - debug, quiet, daemon modes
|
|
* - uid, gid, chroot, nbproc, maxconn
|
|
* 2002/04/08 : 1.1.6
|
|
* - 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
|
|
* 2002/04/03 : 1.1.5
|
|
* - 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.
|
|
* 2002/03/25 : 1.1.4
|
|
* - made rise/fall/interval time configurable
|
|
* 2002/03/22 : 1.1.3
|
|
* - fixed a bug : cr_expire and cw_expire were inverted in CL_STSHUT[WR]
|
|
* which could lead to loops.
|
|
* 2002/03/21 : 1.1.2
|
|
* - 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.

|
|
* 2002/02/12
|
|

|
|
* - it seems that TCP proxies sometimes cannot timeout.
