HAproxy

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.

Release Notes: This new version addresses half of the remaining changes before -final. use_backend now supports log-format expressions. Maps and ACLs now share the same pattern lists which are dynamically updatable from the CLI. SSL supports ALPN and Web sites now load faster thanks to dynamic record size adjustments. Compression of chunked HTTP responses was fixed and enabled again. Other minor features were added and about 35 bugs were fixed.

Release Notes: Two major changes: a rework of the whole polling system to implement a real event cache, and HTTP keep-alive is now enabled by default, so users will no longer be confused by the tunnel mode. Other nice updates include SSL handshake optimizations, more debugging info on the stats socket, the ability to rate-limit SSL to protect the resources, sample fetches to retrieve captured headers, automatic stickiness to the same server after 401/407, and the new "tcp-check connect" directive to check multiple ports on a server. 32 bugs were fixed since dev21.

    Release Notes: This release fixes a few annoying bugs. Use this version instead of 1.5-dev20 to be safe.

    Release Notes: Many new features are included in this version, including server-side keep-alive, maps, use of log-format syntax in redirects, agent-check, tcp-check send/expect, and important memory savings. 71 bugs were fixed. Thanks to the entry of server-side keep-alive, this should be the last development version before the final 1.5 release (unless new bugs appear and require another one).

    Release Notes: This version fixes two possible crashes, one of them remotely triggered (CVE-2013-2175) involving use of a negative occurrence number in hdr_* fetches. Other long-standing improvements were finally merged, such as http-response, dynamic setting of priority, DSCP headers, Netfilter mark and log level, transparent proxy on *BSD, fetching of environment variables, conditional PROXY protocol by ACL, 3 parallel stick-counters instead of 2, reworking of the doc to simplify the search of ACL/fetch keywords, and further-improved configuration error reporting. All 1.5 users must upgrade.
