» Example Usage

resource "aws_wafregional_size_constraint_set" "size_constraint_set" {
  name = "tfsize_constraints"

  size_constraints {
    text_transformation = "NONE"
    comparison_operator = "EQ"
    size                = "4096"

    field_to_match {
      type = "BODY"

» 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.
