  name = "tfsize_constraints"

  size_constraints {

    comparison_operator = "EQ"
    size                = "4096"

    field_to_match {

Nested Blocks

size_constraints

Arguments

• field_to_match - (Required) Specifies where in a web request to look for the size constraint.
• comparison_operator - (Required) The type of comparison you want to perform. e.g. EQ, NE, LT, GT. See docs for all supported values.
• size - (Required) The size in bytes that you want to compare against the size of the specified field_to_match. Valid values are between 0 - 21474836480 bytes (0 - 20 GB).
• text_transformation - (Required) Text transformations used to eliminate unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on field_to_match before inspecting a request for a match. e.g. CMD_LINE, HTML_ENTITY_DECODE or NONE. See docs for all supported values. Note: if you choose BODY as type, you must choose NONE because CloudFront forwards only the first 8192 bytes for inspection.

field_to_match

Arguments

• data - (Optional) When type is HEADER, enter the name of the header that you want to search, e.g. User-Agent or Referer. If type is any other value, omit this field.
• type - (Required) The part of the web request that you want AWS WAF to search for a specified string. e.g. HEADER, METHOD or BODY. See docs for all supported values.

Attributes Reference

In addition to all arguments above, the following attributes are exported:

• id - The ID of the WAF Size Constraint Set.
