Filter which maps the provided linked resources mappings files. These files are used to link a unhashed front end resource like a Javascript or CSS file to a automatically
generated hashed one. The mapping file needs to have the following format for adding a mapping (comments with a # infront and emtpy lines are allowed):
# relative link based on application endpoint system property
/from -> /to
# relative link to absolute URL
/from -> http://localhost:8080/to
The basic flow is that the browser makes a request to the `from` URL and then sends a non cacheable 301 redirect to the browser with the cacheable `to` URL.
