Naming convention of condition primitives

BFE adopts the following naming convention for condition primitives.

Name prefix of condition primitives

• Name prefix of the request primitive is "req_"

  • e.g. req_host_in()

• Name prefix of the response primitive is "res_"

  • e.g. res_code_in()

• Name prefix of the session primitive is "ses_"

  • e.g. ses_vip_in()

• Name prefix of the system primitive is "bfe_"

  • e.g. bfe_time_range()

Name of comparison operations

• match: exact match

  • eg. req_tag_match()

• in: whether an element exists in a set or not

  • eg. req_host_in()

• prefix_in: whether the prefix exists in a set or not

  • eg. req_path_prefix_in()

• suffix_in: whether the suffix exists in a set or not

  • eg. req_path_suffix_in()

• key_exist: whether the specified key exists or not

  • eg. req_query_key_exist()

• value_in: whether the value exists in a set or not

  • eg. req_query_key_exist()

• value_prefix_in: whether the value prefix exists in a set or not

  • eg. req_header_value_prefix_in()

• value_suffix_in: whether the value suffix exists in a set or not

  • eg. req_header_value_suffix_in()

• range: range match

  • eg. req_cip_range()

• regmatch: use regular expression to match

  • eg. req_url_regmatch()
  • Warning: Inappropriate use can significantly affect performance

• contain: string match

  • eg. req_cookie_value_contain()
