Once you have +recompiled or reinstalled OpenSSL with TLS Extensions you will have to recompile mod_ssl +to allow it to recognize SNI support. + +Meanwhile add 'hosts' to your c:\windows\system32\drivers\etc\hosts +or /etc/hosts file as to point the various URL's to your server: +$LST + +and verify that each returns its own name (and an entry in its +own ${DIR}/logs) file). + +NOTE +==== + +Note that in the generated example the 'first' domain is special - and is the +catch all for non-SNI browsers. Depending on your circumstances it may make +sense to use a generic name - and have each of the SNI domains as subdirectories +(and hence URI's under this generic name). Thus allowing non SNI browsers also +access to those sites. +EOM +exit 0 -- cgit v1.2.3
