Use

With this parameter you can configure Modifications of HTTP Requests in the Web Dispatcher or ICM. You can define rules by which the Web Dispatcher/ICM changes the HTTP request before it forwards it (header field manipulation, URL rewrite, and so on)

Structure

Work area	Internet Communication Manager, SAP Web Dispatcher
Unit	Character string
Default value	`icm/HTTP/mod_0 =PREFIX=/` (no action file)
Dynamically changeable	No

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.

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.
