[Bug 65642] New: mod_proxy: retry-directive does not work anymore
https://bz.apache.org/bugzilla/show_bug.cgi?id=65642
Bug ID: 65642
Summary: mod_proxy: retry-directive does not work anymore
Product: Apache httpd-2
Version: 2.4.51
Hardware: Other
Status: NEW
Severity: major
Priority: P2
Component: mod_proxy
Assignee: bugs@httpd.apache.org
Reporter: max.moebius1@gmail.com
Target Milestone: ---
Until Version 2.4.16 (last version I checked) the reverse proxy deactivated a
worker in case the URL was down for "retry"-Seconds.
Configuration:
ProxyPass /YYYYY/XXX/ http://XXX:1234/ retry=5 connectiontimeout=30
Example from 2.4.16 Log (subsequent requests to the same backend are answered
immediately with return-code 503):

after a period of time, or established connection failed because connected host
has failed to respond. : AH00957: HTTP: attempt to connect to y.y.y.y:1234

Current Version 2.4.51 does not respect the retry-setting. It does not disable
the worker. Subsequent requests have to wait for 20s:
