```java
// Configure SSL settings
container.singleton("httpClient", HcHttpClient.class, client -> {
    client.setTrustAllCertificates(true);  // For testing only
});
```

### Debug Logging

Enable debug logging by adding to your logging configuration:

```xml
<logger name="org.codelibs.fess.crawler" level="DEBUG"/>
<logger name="org.codelibs.fess.crawler.client" level="DEBUG"/>

Logging Interceptor
===================

An [OkHttp interceptor][interceptors] which logs HTTP request and response data.

```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();
```

You can change the log level at any time by calling `setLevel()`.
