Synopsis

                     RewriteMap 
                     name 
                     type:source
                  

[server config or <VirtualHost>]

Declares the rewriting map and its type. The map file performs substitutions for various URIs. The name parameter makes up the given name of the mapping. The type and source variables are determined by the type:

txt

A plain-text file, with the source pointing to a regular file

rnd

A plain-text file with a random mapping choice; the source variable points to a regular file

dbm

The source variable points to a DBM-formatted file

int

An internal Apache function; the source variable can be one of two functions: toupper or tolower

prg

A program. The source variable points to a Unix executable

Here is an example that shows how to use a text-based rewriting file:

RewriteMap real-host txt:/usr/local/maps/mymap.txt
