      Returns:
      updated builder instance

    • config

      public BUILDER config(Config config)

      Specified by:
      config in interface Prototype.ConfiguredBuilder<BUILDER extends Http1Config.BuilderBase<BUILDER,PROTOTYPE>,PROTOTYPE extends Http1Config>

      See Also:

    • maxPrologueLength

      public BUILDER maxPrologueLength(int maxPrologueLength)
      Maximal size of received HTTP prologue (GET /path HTTP/1.1).

    • validateRequestHeaders

      public BUILDER validateRequestHeaders(boolean validateRequestHeaders)
      Whether to validate headers. If set to false, any value is accepted, otherwise validates headers + known headers are validated by format (content length is always validated as it is part of protocol processing (other headers may be validated if features use them)).

      Defaults to true.

      Parameters:
      validateRequestHeaders - whether to validate headers
      Returns:
      updated builder instance

      @Deprecated(since="4.1.3", forRemoval=true) public BUILDER validateRequestHostHeader(boolean validateRequestHostHeader)
      Deprecated, for removal: This API element is subject to removal in a future version.
      this switch exists for temporary backward compatible behavior, and will be removed in a future Helidon version
      Request host header validation. When host header is invalid, we return Status.BAD_REQUEST_400.

      The validation is done according to RFC-3986 (see HostValidator). This is a requirement of the HTTP specification.

      This option allows you to disable the "full-blown" validation ("simple" validation is still in - the port must be parseable to integer).

      Parameters:
      validateRequestHostHeader - whether to do a full validation of Host header according to the specification
      Returns:
      updated builder instance
      See Also:

    • validateResponseHeaders

      public BUILDER validateResponseHeaders(boolean validateResponseHeaders)
      Whether to validate headers. If set to false, any value is accepted, otherwise validates headers + known headers are validated by format (content length is always validated as it is part of protocol processing (other headers may be validated if features use them)).

      Defaults to false as user has control on the header creation.

      Parameters:
      validateResponseHeaders - whether to validate headers
      Returns:
      updated builder instance
      See Also:

    • validatePath

      public BUILDER validatePath(boolean validatePath)
      If set to false, any path is accepted (even containing illegal characters).
      Parameters:
