Syntax:
num_map
[$number]
$variable { ... }
Default:
—
Context:
stream
Describes how the values of the specified variable depend on numeric values
or numeric value ranges.
Since variables are evaluated only when used, the mere existence
of even a large number of declared “num_map” variables
does not cause any extra costs for connection processing.
Parameters inside the num_map block specify a mapping
between source and resulting values.
Source values are specified as numbers or as numeric ranges.
The following special parameters are also supported:
default
sets the resulting value if the source value matches none
of the specified variants.
When default is not specified, the default
resulting value will be an empty string.
include
includes a file with values.
There can be several inclusions.
volatile
indicates that the variable is not cacheable.
