// The following comment block elucidates the function of ParseAttributes.

/******************************************************************************
|
|
** Augmented BNF, modified from RFC2109 Section 4.2.2 and RFC2616 Section 2.1
|
|
** please note: this BNF deviates from both specifications, and reflects this
|
|
** implementation. <bnf> indicates a reference to the defined grammar "bnf".
|
|
|
|
** Differences from RFC2109/2616 and explanations:
|
|
1. implied *LWS
|
|
The grammar described by this specification is word-based. Except
|
|
where noted otherwise, linear white space (<LWS>) can be included
|
|
between any two adjacent words (token or quoted-string), and
|
|
between adjacent words and separators, without changing the
|
|
interpretation of a field.
|
|
<LWS> according to spec is SP|HT|CR|LF, but here, we allow only SP | HT.
|
|
|
|
2. We use CR | LF as cookie separators, not ',' per spec, since ',' is in
|
|
common use inside values.
|
|
|
|
3. tokens and values have looser restrictions on allowed characters than
|
|
spec. This is also due to certain characters being in common use inside
|
|
values. We allow only '=' to separate token/value pairs, and ';' to
|
|
terminate tokens or values. <LWS> is allowed within tokens and values
|
|
(see bug 206022).
|
|
|
|
4. where appropriate, full <OCTET>s are allowed, where the spec dictates to
|
|
reject control chars or non-ASCII chars. This is erring on the loose
|
|
side, since there's probably no good reason to enforce this strictness.
|
|
|
|
5. cookie <NAME> is optional, where spec requires it. This is a fairly
|
|
trivial case, but allows the flexibility of setting only a cookie <VALUE>
|
|
with a blank <NAME> and is required by some sites (see bug 169091).
|
|
|
|
6. Attribute "HttpOnly", not covered in the RFCs, is supported
|
|
(see bug 178993).
|
|
|
|
** Begin BNF:
|
|
token = 1*<any allowed-chars except separators>
|
|
value = 1*<any allowed-chars except value-sep>
|
|
separators = ";" | "="
|
|
value-sep = ";"
|
|
cookie-sep = CR | LF
|
|
allowed-chars = <any OCTET except NUL or cookie-sep>
|
|
OCTET = <any 8-bit sequence of data>
|
|
LWS = SP | HT
|
|
NUL = <US-ASCII NUL, null control character (0)>
|
|
CR = <US-ASCII CR, carriage return (13)>
|
|
LF = <US-ASCII LF, linefeed (10)>
|
|
SP = <US-ASCII SP, space (32)>
|
|
HT = <US-ASCII HT, horizontal-tab (9)>
|
|
|
|
set-cookie = "Set-Cookie:" cookies
|
|
cookies = cookie *( cookie-sep cookie )
|
|
cookie = [NAME "="] VALUE *(";" cookie-av) ; cookie NAME/VALUE must come first
|
|
NAME = token ; cookie name
|
|

|

valid values for cookie-av (checked post-parsing) are:
