  /**
   * Configure the server to not perform SSL authentication of the client. This leaves

    OkHttp's request bodies using the boundary only. (This change makes OkHttp more consistent with
    browsers and other HTTP clients.)
 *  New: Drop the `tunnelProxy` argument in `MockWebServer.useHttps()`. This change only impacts
    the OkHttp 5.x API which uses the `mockwebserver3` package.
 *  Fix: Don't call `toDuration()` which isn't available in kotlin-stdlib 1.4.
