專案描述

HAproxy is a high-performance and highly-robust TCP and HTTP load balancer which provides cookie-based persistence, content-based switching, SSL off-loading, advanced traffic regulation with surge protection, automatic failover, run-time regex-based header control, Web-based reporting and management interface, advanced logging to help trouble-shooting buggy applications and/or networks, and a few other features. Its own event-driven state machine achieves 100,000 connections per second and surpasses GigaEthernet on modern hardware, even with tens of thousands of simultaneous connections.

1.4.14

Many bugs were fixed, including http-pretend-keepalive, stuck sessions, balanced url_param with POST requests, incorrect chunk size computations on buffer boundaries, incorrectly set rlimits, incorrect removal of the last header, handling of empty pattern files, and
4GB+ content-length on 32-bit machines. A few improvements were made in the CLI, new ACLs were added, and the efficiency of chunked encoded transfers was improved. All 1.4 users are strongly encouraged to upgrade.

1.4.10

A possible crash when using Cookie-based persistence with appsessions was fixed. Header processing could become wrong after a single reqidel rule removed exactly two headers. Strict aliasing was explicitly disabled to shut down warnings that are emitted with gcc 4.4. Some out-of-memory conditions were not correctly handled in appsession or cookie captures. A native target was added to make builds easier. Users of appsessions are strongly encouraged to upgrade.

1.5-dev3

All fixes from version 1.4.9 were merged. Stickiness tables can now be synchronized between multiple active haproxy nodes. Sticky information is also learned from responses, providing support for SSL-ID. Connections can be accepted over Unix sockets. A new PROXY protocol was implemented to let other components (such as stunnel) pass connection information to haproxy.

1.4.9

Some minor bugs were fixed and several usability improvements were made. The Web interface now allows you to enable or disable servers. The ECV and LDAPv3 checks were merged. The MySQL check was improved to support a real login sequence. Persistence cookies can now be timestamped to support a maximum idle time and a maximum life time, and can be removed by the server if needed (e.g. logout). The SNMP plugin was improved to report socket stats, and some Cacti templates were merged. The halog tool can now instantly report per-URL response times.

1.5-dev1

Support was introduced for per-IP accounting and filtering based on connection counts, rates, byte counts, rates, error counts and rates, and a few other criteria. It is now possible to filter very early at the connection level based on these critieria, resulting in a measured protection capacity of more than 200000 connections per second. This is the first development version of branch 1.5, which should be released around the end of the year. This version is in sync with all the fixes that are available in 1.4.8, and appears reliable enough to be used in production if needed.
