So we have two websites on the same server (same IP, using SNI), siteA has SSL, siteB doesn't. Google will attempt to crawl https://siteB/ (which will return siteA's content! in a browser you would get a warning about the certificate being wrong). Since there are no links anywhere that point to https://siteB why does google crawl it? This is technically a configuration / apache error, but google should not be crawling https websites when their domain does not match the certificate.
