Apache SNI Browser Support

Apache v2.2.12 and OpenSSL v0.9.8j and later support a transport layer security (TLS) called SNI. SNI can secure multiple Apache sites using a single SSL Certificate and use multiple SSL Certificates to secure various websites on a single domain (e.g., www.yourdomain.com, site2.yourdomain.com) or across multiple domains (www.domain1.com, www.domain2.com)—all from a single IP address. For more information on SNI and instructions to set it up, see Using Multiple SSL Certificates in Apache.

Since SNI is fairly new, browsers have only recently supported SNI. We recommend that you review the list below and carefully decide if SNI is a good fit for your SSL websites' requirements.
