The limit Statement

Syntax
limit <value> {
    [ statements ]
}
Description

The limit statement limits the number of requests which are actively being processed through a section. If too many requests are being processed through the limit section, it immediately returns fail.

The <value> text can be a number, or a dynamic expansion, or an attribute reference. The contents of <value> are interpreted as an integer uint32 data type.

Example
limit 4 {
    foo
    bar
}

In general, the best way to use limit is in conjunction with a redundant block. In the following example, the configuration allows 4 packets to be outstanding in the proxy module. If more than 4 packets are outstanding, or if the proxy module fails, the detail module is called.

Example using redundant
redundant
    limit 4 {
        proxy
    }

    detail
}
