* This class comforms to the generic grammar and formatting rules outlined in the * Section 2.2 * and * Section 3.6 * of RFC 2616 *

* 2.2 Basic Rules *

* The following rules are used throughout this specification to describe basic parsing constructs. * The US-ASCII coded character set is defined by ANSI X3.4-1986. *

*
 *     OCTET          = 
 *     CHAR           = 
 *     UPALPHA        = 
 *     LOALPHA        = 
 *     ALPHA          = UPALPHA | LOALPHA
 *     DIGIT          = 
 *     CTL            = 
 *     CR             = 
 *     LF             = 
 *     SP             = 
 *     HT             = 
 *     <">            = 
 * 
*

* Many HTTP/1.1 header field values consist of words separated by LWS or special * characters. These special characters MUST be in a quoted string to be used within * a parameter value (as defined in section 3.6). *

*

 * token          = 1*
 * separators     = "(" | ")" | "<" | ">" | "@"
 *                | "," | ";" | ":" | "\" | <">
 *                | "/" | "[" | "]" | "?" | "="
 *                | "{" | "}" | SP | HT
 * 
*

* A string of text is parsed as a single word if it is quoted using double-quote marks. *

*
 * quoted-string  = ( <"> *(qdtext | quoted-pair ) <"> )
 * qdtext         = >
 * 
*

* The backslash character ("\") MAY be used as a single-character quoting mechanism only * within quoted-string and comment constructs. *

*
 * quoted-pair    = "\" CHAR
 * 
* 3.6 Transfer Codings *

* Parameters are in the form of attribute/value pairs. *

*
 * parameter               = attribute "=" value
 * attribute               = token
 * value                   = token | quoted-string
