AWS负载均衡器可以通过路径匹配规则将请求路由到不同的后端服务。当需要将请求发送到S3存储桶时，可以在路径匹配规则中指定S3存储桶的名称或ARN。使用路径匹配规则可以不使用代理服务器直接将请求发送到S3存储桶，提高请求处理速度并降低成本。

以下是一个示例模板，说明如何使用基于路径的路由将请求发送到S3存储桶：

resource "aws_lb_listener" "example" {
  load_balancer_arn = aws_lb.example.arn
  port              = "80"
  protocol          = "HTTP"

  default_action {
    type             = "fixed-response"
    content_type     = "text/plain"
    status_code      = "404"
    content          = "Not Found"
  }

  # Define a rule that routes requests to S3 bucket "my-bucket"
  # when the path starts with "/my-bucket".
  dynamic "rule" {
    for_each = var.s3_bucket_paths

    content {
      priority          = rule.key + 1
      action_type       = "fixed-response"
      type              = "forward"
      target_group_arn  = aws_lb_target_group.s3_bucket.arn

      forward {
        target_groups {
          target_group_arn = aws_lb_target_group.s3_bucket.arn
          weight           = 100
        }

        stickiness {
          enabled = false
        }

        # The following block specifies the conditions for the rule.
        # Here, we match paths starting with "/my-bucket*".
        # You can modify this block to specify different path match conditions.
        conditions {
          path_patterns = [rule.value + "*"]
        }
      }
    }
  }
}

resource "aws_lb_target_group" "s3_bucket" {
  name_prefix      = "s3-bucket-"
  port             = "80"
  protocol         = "HTTP"
  target_type
