http://sni.velox.ch/httpd-2.2.11-sni.20090427.patch - server name indication support for mod_ssl / Apache 2.2.11 (RFC 4366, section 3.1) Last updated 2009-04-27, by Kaspar Brand. Provided AS IS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND. Based on a patch from the EdelKey project (http://www.edelweb.fr/EdelKey/files/), includes further improvements by Ruediger Pluem (from httpd trunk). Needs openssl-SNAP-20060330 / OpenSSL 0.9.8f or later to work properly (ftp://ftp.openssl.org/snapshot/). OpenSSL versions prior to 0.9.8j must be configured explicitly for TLS extension support at compile time ("./config enable-tlsext").
