 *  **The pingInterval() feature now aggressively checks connectivity for web
    sockets and HTTP/2 connections.**

    Previously if you configured a ping interval that would cause OkHttp to send
    pings, but it did not track whether the reply pongs were received. With this

search_engine.http.ssl.certificate_authorities=
# Username for authenticating to the search engine.
search_engine.username=
# Password for authenticating to the search engine.
search_engine.password=
# Interval (ms) for heartbeat checks to the search engine.
search_engine.heartbeat_interval=10000

# Cipher algorithm used for encryption.
app.cipher.algorism=aes
# Secret key for encryption (change this value for production).
app.cipher.key=___change__me___

     *    }
     * ```
     *
     * This method works like [X509TrustManager.checkServerTrusted] but it receives the hostname of
     * the server as an extra parameter. Regardless of what checks this method performs, OkHttp will
     * always check that the server's certificates match its hostname using the [HostnameVerifier].
     * See [android.net.http.X509TrustManagerExtensions] for more information.
