===================

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()`.

To log to a custom location, pass a `Logger` instance to the constructor.

    // Strip off 2s from this value.
    int shift = Long.numberOfTrailingZeros(product);
    product >>= shift;

    // Use floor(log2(num)) + 1 to prevent overflow of multiplication.
    int productBits = LongMath.log2(product, FLOOR) + 1;
    int bits = LongMath.log2(startingNumber, FLOOR) + 1;
    // Check for the next power of two boundary, to save us a CLZ operation.
    int nextPowerOfTwo = 1 << (bits - 1);

- **Admin Login**: `admin/admin`

## Log Message Guidelines

- Format parameters as `key=value` (e.g., `sessionId={}`, `url={}`)
- Prefix with `[name]` when context identification is needed
- Use full words, not abbreviations (e.g., "documents" not "docs")
