+<para>
+The default value “<value>on</value>” instructs nginx to
+<link id="lingering_timeout">wait for</link> and
+<link id="lingering_time">process</link> additional data from a client
+before fully closing a connection, but only
+if heuristics suggests that a client may be sending more data.
+</para>
+
+<para>
+The value “<value>always</value>” will cause nginx to unconditionally
+wait for and process additional client data.
+</para>
+
+<para>
+The value “<value>off</value>” tells nginx to never wait for
+more data and close the connection immediately.
+This breaks the protocol and should not be used under normal circumstances.

+<para>
+When <link id="lingering_close"/> is in effect, this directive specifies
+a maximum waiting time for more client data to arrive.
+If data are not received during this time, the connection is closed.
+Otherwise, data are read and ignored, then nginx waits again for more data.
+The “wait-read-ignore” cycle is repeated, but no longer than specified by the
+<link id="lingering_time"/> directive.
