| * ChangeLog : | |
| * | |
| * 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. | |
| * - send warnings for servers up/down. | |
| * 2002/03/12 : 1.1.1 | |
| * - fixed a bug in total failure handling | |
| * - fixed a bug in timestamp comparison within same second (tv_cmp_ms) | |
| * 2002/03/10 : 1.1.0 | |
| * - 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. | |
| * 2002/03/08 | |
| * - reworked buffer handling to fix a few rewrite bugs, and | |
| * improve overall performance. | |
| * - implement the "purge" option to delete server cookies in direct mode. | |
| * 2002/03/07 | |
| * - fixed some error cases where the maxfd was not decreased. | |
| * 2002/02/26 | |
| * - now supports transparent proxying, at least on linux 2.4. | |
| * 2002/02/12 | |
| * - 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(). | |
| * 2001/12/30 : release of version 1.0.2 : fixed a bug in header processing | |
| * 2001/12/19 : release of version 1.0.1 : no MSG_NOSIGNAL on solaris | |
| * 2001/12/16 : release of version 1.0.0. | |
| * 2001/12/16 : added syslog capability for each accepted connection. | |

| * 2001/10/31 : added health-check type servers (mode health) which replies OK then closes. | |
| * 2001/10/30 : added the ability to support standard TCP proxies and HTTP proxies | |
| * with or without cookies (use keyword http for this). | |
| * 2001/09/01 : added client/server header replacing with regexps. | |
| * eg: | |
| * cliexp ^(Host:\ [^:]*).* Host:\ \1:80 | |
| * srvexp ^Server:\ .* Server:\ Apache | |
| * 2000/11/29 : first fully working release with complete FSMs and timeouts. | |
| * 2000/11/28 : major rewrite | |
| * 2000/11/26 : first write |
