In OkHttp some fields of the address come from the URL (scheme, hostname, port) and the rest come from the [OkHttpClient](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-ok-http-client/).

### [Routes](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-route/)

   HTTP to HTTPS.


## Version 1.1.0

_2013-06-15_

 * Fix: Connection reuse was broken for most HTTPS connections due to a bug in
   the way the hostname verifier was selected.
 * Fix: Locking bug in SpdyConnection.
 * Fix: Ignore null header values (for compatibility with HttpURLConnection).
 * Add URLStreamHandlerFactory support so that `URL.openConnection()` uses

    this.skipAll(timeout, timeUnit)
  } catch (_: IOException) {
    false
  }
