As a follow up to the cookie versions,
try
cookie1.setVersion(int inVersion);
and
int version = cookie1.getVersion();
With version 0 cookies, values should not contain the following: whitespace,
brackets and parens, equal signs, commas, double quotes, slashes, question
marks, at signs, colons, and semicolons. Empty values may not behave the
same way on all browsers.
I believe that version 0 is the default when a cookie is instantiated.
Version 1 has fever restrictions on the values of the cookies.

Well, depending on what version of cookies you're using, certain
characters are not allowed in cookie values. I had a problem with
this some time back. By Netscape's original spec (version 0), most
characters are allowed (with the exception of a few, like ' ' and ',',
I don't recall exactly). With the new cookie spec (RFC 2109, version
1), there are many more disallowed characters, including "=" (the
restrictions amount to saying that the cookie value must be a valid
HTTP 1.1 "token"). Technically, the JSDK was supposed to allow
cookies of both types (and even had a "version" parameter), but it did
have some problems with that -- it would throw
IllegalArgumentException's when encountering cookies with the
disallowed characters. If you take a look at the Cookie.java source,
you can see all this. Although, I don't know whether this problem has
been addressed in more recent JSDK versions. Are you getting any
IllegalArgumentException's?
