Foreman and Keep-alive

Support
1

Hi all,

Is the Foreman keep-alive feature safe to turn on? I'm running stable
Foreman 1.11.4 on Centos 6 behind haproxy. I can turn on TCP/HTTP
keep-alive for haproxy side, but foreman apache default sets 'keep-alive'
to 'off'. is the passenger/puppet safe enough for apache to enable
'keep-alive'?

Also, since 'keep-alive' is off by default, then the following settings
will have no effects, right?

MaxKeepAliveRequests 100
KeepAliveTimeout 15

By the way, does a puppet agent leverage foreman puppet master's keep-alive
feature, or turn it off by default (similar to '–no-http-keep-alive' to
wget)? Thanks.

Best,
Thomas

Keepalive is enabled on the Foreman vhost by default in the 1.12.0
installer, Refactor #8489: Set KeepAlive to on - Installer - Foreman. I can't comment
on whether you should use it on the Puppet vhost.

It has no effect:
