Tools like
https://sslanalyzer.comodoca.com/?url=www.google.com
report that for www.google.com, "SSL v3.0 not supported" (presumably disabled because of the associated security holes).

In that case, how come when I use LWP::UserAgent to make an https request with $ENV{HTTPS_DEBUG} set to true, the debug output appears to indicate that SSLv3 was negotiated successfully?

www:/var/www/html# perl -e 'use LWP::UserAgent; $ENV{HTTPS_DEBUG} = 1;
+ my $ua = new LWP::UserAgent; $ua->get("https://www.google.com/");'
SSL_connect:before/connect initialization
SSL_connect:SSLv2/v3 write client hello A
SSL_connect:SSLv3 read server hello A
SSL_connect:SSLv3 read server certificate A
SSL_connect:SSLv3 read server done A
SSL_connect:SSLv3 write client key exchange A
SSL_connect:SSLv3 write change cipher spec A
SSL_connect:SSLv3 write finished A
SSL_connect:SSLv3 flush data
SSL_connect:SSLv3 read finished A

In reply to if SSLv3 is disabled, why does LWP::UserAgent request indicate successful SSLv3 handshake? by bennetthaselton
