- Traffic Shaping
Description¶
Starting with 1.3.8, lighttpd supports limiting the bandwidth for a single connection or config context like a virtual host or a URL.
Options¶
connection.kbytes-per-second
Limit the throughput for each single connection to the given limit in kbyte/s
Default: 0 (no limit)
server.kbytes-per-second
Limit the throughput for all connections to the given limit in kbyte/s
Default: 0 (no limit)
If you want to specify a limit for a special virtual server use:
$HTTP["host"] == "www.example.org" { server.kbytes-per-second = 128 }
which will override the default for this host.
Note:
Keep in mind that a limit below 32kb/s might actually limit the traffic to 32kb/s.
This is caused by the size of the TCP send buffer.
Selective traffic shaping defined by backend script¶
Since lighttpd 1.4.46 (#954)) a backend script can selectively request traffic shaping on a per-request basis. You can e.g. use php and do:
<?php header("X-LIGHTTPD-KBytes-per-second: 50"); header("X-Sendfile: /path/to/file"); ?>
to set the speed of the current response.
