    The SSL authentication is enabled by default meaning that hostname verification and certificate chain validation is done using the JVM default settings.
    
    Returns:
    
    this ClientBuilder object for setting additional options
    
    Throws:
    
    java.lang.IllegalStateException - if customSSLSocketFactory(SSLSocketFactory) has been called on this ClientBuilder

  - interceptors
```
public ClientBuilder interceptors(HttpConnectionInterceptor... interceptors)
```
    This method adds HttpConnectionInterceptors to be used on the CloudantClient connection. Interceptors can be used to modify the HTTP requests and responses between the CloudantClient and the server.
    An example interceptor use might be to apply a custom authorization mechanism. For instance to use BasicAuth instead of CookieAuth it is possible to use a BasicAuthInterceptor that adds the BasicAuth Authorization header to the request:
```
 
 CloudantClient client = ClientBuilder.account("yourCloudantAccount")
      .interceptors(new BasicAuthInterceptor("yourUsername:yourPassword"))
      .build()
 
 
```
    Parameters:
    
    interceptors - one or more HttpConnectionInterceptor objects
    
    Returns:
    
    this ClientBuilder object for setting additional options
    
    See Also:
    
    HttpConnectionInterceptor
  - connectTimeout
```
public ClientBuilder connectTimeout(long connectTimeout,
                                    java.util.concurrent.TimeUnit connectTimeoutUnit)
```
    Sets the specified timeout value when opening the client connection. If the timeout expires before the connection can be established, a SocketTimeoutException is raised.
    Example creating a CloudantClient with a connection timeout of 2 seconds:
```
 
 CloudantClient client = ClientBuilder.account("yourCloudantAccount")
      .username("yourUsername")
      .password("yourPassword")
      .connectTimeout(2, TimeUnit.SECONDS)
      .build();
 
 
```
    Defaults to DEFAULT_CONNECTION_TIMEOUT with TimeUnit.MINUTES.
    Parameters:
    
    connectTimeout - duration of the read timeout
    
    connectTimeoutUnit - unit of measurement of the read timeout parameter
    
    Returns:
    
    this ClientBuilder object for setting additional options
    
    See Also:
    
    URLConnection.setConnectTimeout(int)
  - readTimeout
```
public ClientBuilder readTimeout(long readTimeout,
                                 java.util.concurrent.TimeUnit readTimeoutUnit)
```
    Sets the specified timeout value when reading from a InputStream with an established client connection. If the timeout expires before there is data available for read, a SocketTimeoutException is raised.
    Example creating a CloudantClient with a read timeout of 2 seconds:
```
 
 CloudantClient client = ClientBuilder.account("yourCloudantAccount")
      .username("yourUsername")
      .password("yourPassword")
      .readTimeout(2, TimeUnit.SECONDS)
      .build();
 
 
```
    Defaults to DEFAULT_READ_TIMEOUT with TimeUnit.MINUTES.
    Parameters:
    
    readTimeout - duration of the read timeout
    
    readTimeoutUnit - unit of measurement of the read timeout parameter
    
    Returns:
    
    this ClientBuilder object for setting additional options
