The quoted string fields parsing done in squid3 using the
httpHeaderParseQuotedString function (HttpHeaderTools.cc file)
I found that we do not support multiline quoted string fields, but
according the rfc2616 multiline quoted string fields should supported:
quoted-string = ( <"> *(qdtext | quoted-pair ) <"> )
qdtext = <any TEXT except <">>
TEXT = <any OCTET except CTLs,
but including LWS>
LWS = [CRLF] 1*( SP | HT
I am planning to fix the httpHeaderParseQuotedString function, using one
of the following rules:
1) Just ignore any "\r" or "\n" character. This is the fastest and
simpler approach
3) Require "\r\n " or "\r\n\t" as line separator and just remove the "\r\n"
3) Require "\r\n " or "\r\n\t" as line separator and replace it with a
space
4) Also support "\n\t" or "\n\n\t" as line separators.
(4) case #2 "\n\n\t" is also non-compliant.
Any comments or suggestions?
RFC states "A recipient MAY replace any linear white space with a single
SP".
So (1) and the second (3) {replace with 0x20} are the valid options.
It may be worth having two quoted-string parsers. One for each option.
The preference being (1) for its higher performance.
