## RULE DEFINITIONS AND PRIVILEGED SETTINGS

- replace\_tag tagname expression

  Assign a valid regular expression to tagname.

  Note: It is not recommended to put quantifiers inside the tag, it's better to put them inside the rule itself for greater flexibility.

- replace\_pre tagname expression

  Assign a valid regular expression to tagname.  The expression will be placed before each tag that is replaced.

- replace\_inter tagname expression

  Assign a valid regular expression to tagname.  The expression will be placed between each two immediately adjacent tags that are replaced.

- replace\_post tagname expression

  Assign a valid regular expression to tagname.  The expression will be placed after each tag that is replaced.

- replace\_rules list\_of\_tests

  Specify a list of symbolic test names (separated by whitespace) of tests which should be modified using replacement tags.  Only simple regular expression body, header, uri, full, rawbody tests are supported.

- replace\_start string

  - replace\_end string

  String(s) which indicate the start and end of a tag inside a rule.  Only tags enclosed by the start and end strings are found and replaced.
