  • OVERWRITE_IF_EXISTS: Search for the specified header and replace its value
  • OVERWRITE_IF_EXISTS_OR_ADD: Search for the specified header and replace its value or add the header if it does not exist yet
  • REMOVE: Search for the specified header and remove it

For more information about these action, please check the api reference.
