Yes, that works.

FWIW, here are the interesting options to get a good score at Qualys'
SSL labs test at https://www.ssllabs.com/ssldb/index.html (assumed
certificate is not self signed and private key is long enough)

# Enable Strict-Transport-Security (means client should only use
HTTP/SSL)
Header set Strict-Transport-Security "max-age=15768000"

# Enable Session redumption (SSL speedup)
SSLSessionCache         dbm:/var/db/httpd/mod_ssl_scache
SSLSessionCacheTimeout  300

# Disable vulnerable SSLv2 and alorighms < 128 bits.
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM

It seems enabling SSLv3 costs a few points. Is SSLv3 really vulnerable?
As I understand there are clients out of there that do not support
TLSv1, therefore disabling SSLv3 is a security vs compatibility tradeof.
Anyone is knowledgable about that?
