<module xmlns="urn:lighttpd.net:lighttpd2/doc1">
<short>balances between different backends.</short>
<description>
Using an action from mod_balance also activates a backlog: lighttpd2 will then put requests in a backlog if no backend is available and try again later.
Be careful: the referenced actions may get executed more than once (until one is successful!), so don't loop rewrites in them or something similar.

<action name="balance.rr">
<short>balance between actions (list or single action) with Round-Robin</short>
<parameter name="actions">
<short>the actions to balance between</short>
</parameter>
<description>
Round-Robin (rr) the requests are distributed equally over all backends.
</description>
<example>
<config>
balance.rr { fastcgi "127.0.0.1:9090"; };
</config>
</example>
<example>
<config>
balance.rr ({ fastcgi "127.0.0.1:9090"; }, { fastcgi "127.0.0.1:9091"; });
</config>
</example>
</action>
<action name="balance.sqf">
<short>balance between actions (list or single action) with SQF</short>
<parameter name="actions">
<short>the actions to balance between</short>
</parameter>
<description>
Shortest-Queue-First (sqf) is similar to Round-Robin and prefers the backend with the shortest wait-queue.
</description>
<example>
<config>
balance.sqf { fastcgi "127.0.0.1:9090"; };
</config>
</example>
</action>
<option name="balance.debug">
