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.

44: * message-header = field-name ":" [ field-value ]
45: * field-name = token
46: * field-value = *( field-content | LWS )

48: * and consisting of either *TEXT or combinations
