26 <description>Provides better support for systemd integration</description>

32 <p>This module provides support for systemd integration. It allows
33 starting httpd as a service with systemd <code>Type=notify</code>
34 (see systemd.service(5) manual page for more information). It also
35 provides statistics in <code>systemctl status</code> output and adds
36 various directives useful for systemd integration.
41 <name>IdleShutdown</name>
42 <description>Enable shutting down the httpd when it is idle for some time.</description>
43 <syntax>IdleShutdown seconds</syntax>
44 <default>IdleShutdown 0</default>
45 <contextlist><context>server config</context></contextlist>
48 <p>The <directive>IdleShutdown</directive> directive enables shutting
49 down the httpd when it is idle for some time. The idleness is based on
50 bytes served, so if there are no bytes sent for some time defined by this
51 directive, httpd will shutdown. By default, IdleShutdown is set to 0
52 meaning this feature is disabled.
55 <p>This feature is useful in a combination with systemd socket activation
56 (see systemd.socket(5) manual page). When httpd is started by systemd on
57 some request, using this directive you can stop the httpd automatically
58 when all the requests are served.
61 <note type="warning"><title>Implementation warning</title><p>
62 Because of implementation details, idleness is checked only every 10
63 seconds. That means that if you specify <code>IdleShutdown 14</code>,
64 httpd will stop itself after 20 seconds of idleness.
