I'm trying to sort out some OCSP issues I appear to be getting and found ssllabs.com which tests your SSL certificates with a variety of browsers and platforms which is really useful. However, for each of the domains I test, it's picking up a second certificate. This second certificate is for another domain I also host. It fails of course due to the mismatched name, but concerns me as there appears to be something somewhere linking sites together when I thought they should be totally separate. Example: https://www.ssllabs.com/ssltest/analyze.html?d=xavbroadcast.co.uk&s=18.104.22.168&hideResults=on I'm not too sure where to look. Any ideas?
