  1. sub_filter
  2. sub_filter_last_modified
  3. sub_filter_once
  4. sub_filter_types

Sets a string to replace and a replacement string. The string to replace is matched ignoring the case. The string to replace (1.9.4) and replacement string can contain variables. Several sub_filter directives can be specified on the same configuration level (1.9.4). These directives are inherited from the previous configuration level if and only if there are no sub_filter directives defined on the current level.
