Value Range and Syntax

The parameter has the following syntax:

icm/HTTP/mod_<xx> = PREFIX=<URL prefix>[, FILE=<action file>]

<xx> must be specified in ascending order from 0 .

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
