KeepAliveTimeout - no effect through ISPConfig

[ISPConfigFan]

Once again, good evening...

While finetuning Keepalive settings i noticed something strange; don't know if it's a bug or something i just don't realize, but here's the deal:

Keepalive is set to off in the /etc/httpd/conf/httpd.conf
Keepalivetimeout was set to 100 in same file - but has no effect you would say

Keepalive is set to On in vhost through ISPConfig (static content website, very small icons etc)
Keepalivetimeout is set to 5 in same vhost directives

But still 'server-status' showed a lot of K's, remaining in same slots. With nearly 1000 users online at same time this filled up the max-clients within notime.

Now when i changed the Keepalivetimeout in the main apache httpd.conf to 5, suddenly slots are free within 5 seconds as they supposed to be.

It seems like the ISPConfig vhost apache directive Keepalivetimeout has no effect, but the main httpd.conf does...

Running ISPConfig 2.2.11

[till]

I have no idea, it should work in the vhosts too according to the apache documentation, there is nothing special in ISPConfig compared to a non ISPConfig apache vhost configuartion.

Yes that's what i read too and therefore it took some time to find out what caused the problem.

Just wanted to let you know though.
