 * This class tracks header values line-by-line. A field with multiple comma- separated values on
 * the same line will be treated as a field with a single value by this class. It is the caller's
 * responsibility to detect and split on commas if their field permits multiple values. This
 * simplifies use of single-valued fields whose values routinely contain commas, such as cookies or
 * dates.

CoreLib supports multiple logging frameworks. Configure your preferred logger:

```java
// Use with SLF4J (add slf4j-api dependency)
Logger logger = Logger.getLogger(MyClass.class);

// Use with Commons Logging (add commons-logging dependency)  
Logger logger = Logger.getLogger(MyClass.class);

// Use with Java Util Logging (built-in)
Logger logger = Logger.getLogger(MyClass.class.getName());
```
