Value Range and Syntax
The parameter has the following syntax:
icm/HTTP/mod_<xx> = PREFIX=<URL prefix>[, FILE=<action file>]
The <xx> index is a number without a leading 0. You do not need to use the indexes in ascending order; that is, you can, for example, configure only icm/HTTP/mod_2.
Option FILE
With the optional parameter FILE you can specify the action file with the rules to apply. If only a file name without the full path is specified, the file must be in the working directory of the process.
The action file is a text file with one action (rule) per line. Comment lines begin with a hash sign (#).
You can find an example of an action file in Defining Modification Actions.
SAP Recommendation
To have the same filter rules on all instances, store the file with the filter rules in a global directory and set the parameter in the default profile DEFAULT.PFL.
Example
The filter rules are in file icm_filter_rules.txt in directory $(DIR_GLOBAL)/security/data
icm/HTTP/mod_0 = PREFIX=/,FILE=$(DIR_GLOBAL)/security/data/icm_filter_rules.txt
