| A simple class encapsulating an attribute/value pair.
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
