 | `bindingInformation` | Required string attribute.<br><br>Specifies information to communicate with a site. For example, a Web site binding includes the IP address (or unspecified IP addresses), the port number, and an optional host header used to communicate with the site. |
 | `protocol` | Required string attribute.<br><br>Specifies the protocol for communicating with a site. |

Only one certificate can be bound to a combination of IP address and the port.</li> <li>A value of "1" specifies that the secure connection be made using the port number and the host name obtained by using Server Name Indication (SNI).</li> <li>A value of "2" specifies that the secure connection be made using the centralized SSL certificate store without requiring a Server Name Indicator.</li> <li>A value of "3" specifies that the secure connection be made using the centralized SSL certificate store while requiring Server Name Indicator</li></ul> Centralized SSL certificate support enables you to create a centralized certificate store that can contain multiple certificate files. You can name the certificate files to correspond to the host names that they contain. This enables you to create a binding that only requires a port, rather than an IP/port or a host name/port combination. When a request comes in, IIS matches the port, determines the host name from the request, and searches the centralized certificate store for a certificate file with a matching name. It uses that certificate. <br><br> With a Server Name Indicator (SNI), the host name is exchanged as part of the SSL handshake. SNI is enabled in the Add Site Binding dialog box when you add a binding with a type of HTTPS. This is especially useful for SSL connections that host multiple servers on a single network address. For more information, see [IIS 8.0 Server Name Indication (SNI): SSL Scalability](/iis/get-started/whats-new-in-iis-8/iis-80-server-name-indication-sni-ssl-scalability). <br><br>The sslFlags attribute is only set when the protocol is **https**.

Only one certificate can be bound to a combination of IP address and the port.</td></tr> <tr> <th><code>1</code></th> <td>The secure connection made using the port number and the host name obtained by using Server Name Indication (SNI).</td></tr> <tr> <th><code>2</code></th> <td>The secure connection be made using the centralized SSL certificate store.</td></tr> <tr> <th><code>4</code></th> <td>Disable HTTP/2.</td></tr> <tr> <th><code>8</code></th> <td>Disable OCSP Stapling.</td></tr> <tr> <th><code>16</code></th> <td>Disable QUIC.</td></tr> <tr> <th><code>32</code></th> <td>Disable TLS 1.3 over TCP.</td></tr> <tr> <th><code>64</code></th> <td>Disable Legacy TLS.</td></tr> </tbody></table> Centralized SSL certificate support enables creating a centralized certificate store that can contain multiple certificate files.

The default value is `0`. |
