Fedora Update Notification
FEDORA-2026-d790d66a08

--------------------------------------------------------------------------------

Name        : haproxy
Product     : Fedora 42
Version     : 3.0.23
Release     : 2.fc42
URL         : https://www.haproxy.org/
Summary     : Reliable, high-performance TCP/HTTP load-balancing reverse proxy
Description :
HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high
availability environments. Indeed, it can:
 - route HTTP requests depending on statically assigned cookies
 - spread load among several servers while assuring server persistence
   through the use of HTTP cookies
 - switch to backup servers in the event a main one fails
 - accept connections to special ports dedicated to service monitoring
 - stop accepting connections without breaking existing ones
 - add, modify, and delete HTTP headers in both directions
 - block requests matching particular patterns
 - report detailed status to authenticated users from a URI intercepted
   from the application
