------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2021-3ab4512c98 2021-08-26 21:09:57.867706 ------------------------------------------------------------------------------- -
Name : haproxy Product : Fedora 33 Version : 2.2.16 Release : 1.fc33 URL : http://www.haproxy.org/ Summary : HAProxy reverse proxy for high availability environments 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
