## Version 4.4.1

_2020-03-08_

 *  Fix: Don't reuse a connection on redirect if certs match but DNS does not. For better
    locality and performance OkHttp attempts to use the same pooled connection across redirects and
    follow-ups. It independently shares connections when the IP addresses and certificates match,
    even if the host names do not. In 4.4.0 we introduced a regression where we shared a connection

    }

    // Optimization: check whether hostname is too short to match the pattern. hostName must be at
    // least as long as the pattern because asterisk must match the whole left-most label and
    // hostname starts with a non-empty label. Thus, asterisk has to match one or more characters.
    if (hostname.length < pattern.length) {
      return false // Hostname too short to match the pattern.
