no regression, if you do this

c.setVersion(1);
response.addCookie(c);
then it works just fine.
however, if you do
c = new javax.servlet.http.Cookie("abcv0","123==");
response.addCookie(c);
then it doesn't. if we encode it, (which we did at our first attempt for
v0 cookies) we actually don't pass the TCK.
only v1 cookies should be double quoted, in previous versions of tomcat,
I believe everything got double quoted, regardless of version on the cookie.
v0 cookies, the spec says
/NAME/=/VALUE/
This string is a sequence of characters excluding semi-colon, comma
and white space. If there is a need to place such data in the name
or value, some encoding method such as URL style %XX encoding is
recommended, though no encoding is defined or required.
the problem was that encoding wasn't defined nor required. so when we
followed the spec, and added %XX encoding, TCK tests failed.
at this point I would say, we handle cookies correctly. if one needs ==
at the end of the cookie, then they need to use v1 cookies, according to
spec
I find the regressions caused by the new behavior problematic, and it
will cause lots of problems with existing applications, since the
default cookie version used is version 0.
As I'm the only one complaining at the moment, I think I'll take my
concerns elsewhere, no problem, I get the idea :) Obviously, when I say
"encoding", I am not talking about quoting the whole value (or name) as
was done before.
as always, I'm open to suggestions. it'd be easier if you suggested
something.
here is the javadoc for the servlet spec
setValue
public void *setValue*(String
<http://java.sun.com/j2se/1.5/docs/api/java/lang/String.html> newValue)
Assigns a new value to a cookie after the cookie is created. If you
use a binary value, you may want to use BASE64 encoding.
With Version 0 cookies, values should not contain white space,
brackets, parentheses, equals signs, commas, double quotes, slashes,
question marks, at signs, colons, and semicolons. Empty values may
not behave the same way on all browsers.
*Parameters:*
|newValue| - a |String| specifying the new value
*See Also:*
|getValue()|
<http://java.sun.com/javaee/5/docs/api/javax/servlet/http/Cookie.html#getValue%28%29>,
|Cookie|
<http://java.sun.com/javaee/5/docs/api/javax/servlet/http/Cookie.html>
I guess we could throw a run time exception if the value contained any
of those. other than that, I'm not sure how to behave
