All Implemented Interfaces:

Iterable<HttpField>
```
public class HttpFields
extends Object
implements Iterable<HttpField>
```
HTTP Fields. A collection of HTTP header and or Trailer fields.
This class is not synchronized as it is expected that modifications will only be performed by a single thread.
The cookie handling provided by this class is guided by the Servlet specification and RFC6265.
