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
}

}
