    • comparisonOperator

      @Stability(Stable) public CfnSizeConstraintSet.SizeConstraintProperty.Builder comparisonOperator(String comparisonOperator)
      Sets the value of CfnSizeConstraintSet.SizeConstraintProperty.getComparisonOperator()
      Parameters:
      comparisonOperator - The type of comparison you want AWS WAF to perform. This parameter is required. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of " Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.

      EQ : Used to test if the Size is equal to the size of the FieldToMatch

      NE : Used to test if the Size is not equal to the size of the FieldToMatch

      LE : Used to test if the Size is less than or equal to the size of the FieldToMatch

      LT : Used to test if the Size is strictly less than the size of the FieldToMatch

      GE : Used to test if the Size is greater than or equal to the size of the FieldToMatch

      GT : Used to test if the Size is strictly greater than the size of the FieldToMatch

      Returns:
      this

    • fieldToMatch

      @Stability(Stable) public CfnSizeConstraintSet.SizeConstraintProperty.Builder fieldToMatch(IResolvable fieldToMatch)
      Sets the value of CfnSizeConstraintSet.SizeConstraintProperty.getFieldToMatch()
      Parameters:
      fieldToMatch - The part of a web request that you want to inspect, such as a specified header or a query string. This parameter is required.
      Returns:
      this

    • fieldToMatch

      @Stability(Stable) public CfnSizeConstraintSet.SizeConstraintProperty.Builder fieldToMatch(CfnSizeConstraintSet.FieldToMatchProperty fieldToMatch)
      Sets the value of CfnSizeConstraintSet.SizeConstraintProperty.getFieldToMatch()
      Parameters:
      fieldToMatch - The part of a web request that you want to inspect, such as a specified header or a query string. This parameter is required.
      Returns:
      this

    • size

      @Stability(Stable) public CfnSizeConstraintSet.SizeConstraintProperty.Builder size(Number size)
      Sets the value of CfnSizeConstraintSet.SizeConstraintProperty.getSize()
      Parameters:
      size - The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch . This parameter is required. AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of " Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.

      Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).

      If you specify URI for the value of Type , the / in the URI path that you specify counts as one character. For example, the URI /logo.jpg is nine characters long.

      Returns:
      this

    • textTransformation

      @Stability(Stable) public CfnSizeConstraintSet.SizeConstraintProperty.Builder textTransformation(String textTransformation)
      Sets the value of CfnSizeConstraintSet.SizeConstraintProperty.getTextTransformation()
      Parameters:
      textTransformation - Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF . This parameter is required. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

      You can only specify a single type of TextTransformation.

      Note that if you choose BODY for the value of Type , you must choose NONE for TextTransformation because Amazon CloudFront forwards only the first 8192 bytes for inspection.

      NONE

      Specify NONE if you don't want to perform any text transformations.

      CMD_LINE

      When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

      • Delete the following characters: \ " ' ^
      • Delete spaces before the following characters: / (
      • Replace the following characters with a space: , ;
      • Replace multiple spaces with one space
      • Convert uppercase letters (A-Z) to lowercase (a-z)

      COMPRESS_WHITE_SPACE

      Use this option to replace the following characters with a space character (decimal 32):

      • \f, formfeed, decimal 12
      • \t, tab, decimal 9
      • \n, newline, decimal 10
      • \r, carriage return, decimal 13
      • \v, vertical tab, decimal 11
      • non-breaking space, decimal 160

      COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

      HTML_ENTITY_DECODE

      Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

      • Replaces (ampersand)quot; with "
      • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
      • Replaces (ampersand)lt; with a "less than" symbol
      • Replaces (ampersand)gt; with >
      • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
      • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters

      LOWERCASE

      Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

      URL_DECODE

      Use this option to decode a URL-encoded value.

      Returns:
      this
