Name : haproxy
Product : Fedora 34
Version : 2.3.13
Release : 1.fc34
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
