The value is <code>true</code> or <code>false</code>. The default is <code>false</code>.</p> </li> </ul> <p>The following attributes are supported by both Application Load Balancers and Network Load Balancers:</p> <ul> <li> <p> <code>access_logs.s3.enabled</code> - Indicates whether access logs are enabled. The value is <code>true</code> or <code>false</code>. The default is <code>false</code>.</p> </li> <li> <p> <code>access_logs.s3.bucket</code> - The name of the S3 bucket for the access logs. This attribute is required if access logs are enabled. The bucket must exist in the same region as the load balancer and have a bucket policy that grants Elastic Load Balancing permissions to write to the bucket.</p> </li> <li> <p> <code>access_logs.s3.prefix</code> - The prefix for the location in the S3 bucket for the access logs.</p> </li> </ul> <p>The following attributes are supported by only Application Load Balancers:</p> <ul> <li> <p> <code>idle_timeout.timeout_seconds</code> - The idle timeout value, in seconds. The valid range is 1-4000 seconds. The default is 60 seconds.</p> </li> <li> <p> <code>routing.http.desync_mitigation_mode</code> - Determines how the load balancer handles requests that might pose a security risk to your application. The possible values are <code>monitor</code>, <code>defensive</code>, and <code>strictest</code>. The default is <code>defensive</code>.</p> </li> <li> <p> <code>routing.http.drop_invalid_header_fields.enabled</code> - Indicates whether HTTP headers with invalid header fields are removed by the load balancer (<code>true</code>) or routed to targets (<code>false</code>). The default is <code>false</code>.</p> </li> <li> <p> <code>routing.http.x_amzn_tls_version_and_cipher_suite.enabled</code> - Indicates whether the two headers (<code>x-amzn-tls-version</code> and <code>x-amzn-tls-cipher-suite</code>), which contain information about the negotiated TLS version and cipher suite, are added to the client request before sending it to the target. The <code>x-amzn-tls-version</code> header has information about the TLS protocol version negotiated with the client, and the <code>x-amzn-tls-cipher-suite</code> header has information about the cipher suite negotiated with the client. Both headers are in OpenSSL format. The possible values for the attribute are <code>true</code> and <code>false</code>. The default is <code>false</code>.</p> </li> <li> <p> <code>routing.http2.enabled</code> - Indicates whether HTTP/2 is enabled. The value is <code>true</code> or <code>false</code>. The default is <code>true</code>. Elastic Load Balancing requires that message header names contain only alphanumeric characters and hyphens.</p> </li> <li> <p> <code>waf.fail_open.enabled</code> - Indicates whether to allow a WAF-enabled load balancer to route requests to targets if it is unable to forward the request to Amazon Web Services WAF. The value is <code>true</code> or <code>false</code>. The default is <code>false</code>.</p> </li> </ul> <p>The following attribute is supported by Network Load Balancers and Gateway Load Balancers:</p> <ul> <li> <p> <code>load_balancing.cross_zone.enabled</code> - Indicates whether cross-zone load balancing is enabled. The value is <code>true</code> or <code>false</code>. The default is <code>false</code>.</p> </li> </ul>"
