Dear squid users.

When using a client like LINKS against Squid v3.2 and v2.7 with default logformat Squid only escape the apostrophes in the URL with %27 in the access.log with v2.7 and not with v3.2
I assume clients like FF/IE escape the URL before passing it to Squid ?
Yes.
Is this a possible bug in Squid v3.2 since Squid 2.7 does the proper escaping before logging it to access.log.
The reason I'm asking is, I have a daemon as logger and now need to escape the URL value in the daemon since Squid v3.2.
Who must escape the URL the client or Squid ?
Depends n which RFC they are following.
RFC 1738 states apostrophe (%27) is not a reserved character ad can be
ignored completely
"
Thus, only alphanumerics, the special characters "$-_.+!*'(),", and
reserved characters used for their reserved purposes may be used
unencoded within a URL.
"
RFC 3986 names apostrophe a reserved sub-delim
"
characters in the reserved
set are protected from normalization and are therefore safe to be
used by scheme-specific and producer-specific algorithms for
delimiting data subcomponents within a URI.
"
and
"
URI producing applications should percent-encode data octets that
correspond to characters in the reserved set unless these characters
are specifically allowed by the URI scheme to represent data in that
component.
"
In regard to this character squid complies with both.
