public interface Header
Represents an HTTP header field.

The HTTP header fields follow the same generic format as that given in Section 3.1 of RFC 822. Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive. The field value MAY be preceded by any amount of LWS, though a single SP is preferred. 

     message-header = field-name ":" [ field-value ]
     field-name     = token
     field-value    = *( field-content | LWS )
     field-content  = <the OCTETs making up the field-value
                      and consisting of either *TEXT or combinations
                      of token, separators, and quoted-string>
