10.5.5. KeepAlive
KeepAlive
sets whether the server allows more than one request per connection and can be used to prevent any one client from consuming too much of the server's resources.
By default
Keepalive
is set to off
. If Keepalive
is set to on
and the server becomes very busy, the server can quickly spawn the maximum number of child processes. In this situation, the server slows down significantly. If Keepalive
is enabled, it is a good idea to set the the KeepAliveTimeout
low (refer to Section 10.5.7, “ KeepAliveTimeout
” for more information about the KeepAliveTimeout
directive) and monitor the /var/log/httpd/error_log
log file on the server. This log reports when the server is running out of child processes.
