34/**
35 * Represents an HTTP header field.
36 *
37 * <p>The HTTP header fields follow the same generic format as
38 * that given in Section 3.1 of RFC 822. Each header field consists
39 * of a name followed by a colon (":") and the field value. Field names
40 * are case-insensitive. The field value MAY be preceded by any amount
41 * of LWS, though a single SP is preferred.
42 *
43 *<pre>
44 *     message-header = field-name ":" [ field-value ]
45 *     field-name     = token
46 *     field-value    = *( field-content | LWS )
47 *     field-content  = &lt;the OCTETs making up the field-value
48 *                      and consisting of either *TEXT or combinations
49 *                      of token, separators, and quoted-string&gt;
