Can't set session cookie???

[Brett]

I'd like to set a session cookie that expires once the browser is
closed. I've tried:

document.cookie = "wm_javascript= " + escape("SomeNam e|" +
window.document .referrer);

with no expires. This doesn't set a cookie. It seems I must put in
an expiration for the cookie to set. The code below does work:

var the_name = window.document .referrer;
var the_cookie = "wm_javascript= " + escape("SomeNam e|" + the_name);
var the_date = new Date("December 31, 2050");
var the_cookie_date = the_date.toGMTS tring();
the_cookie = the_cookie + ";expires=" + the_date.toGMTS tring();
document.cookie = the_cookie;

Why doesn't the session cookie set? I'm using IE6.

Also, if a user has multiple IE windows open, will the session cookie
expires only after all IE windows have closed?

Thanks,
Brett

document.referr er is unreliable and using it is error-prone.

Using date strings is error-prone because interpretation is
implementation-dependent. Use several arguments instead:

var the_date = new Date(2050, 11, 31);

Implementations usually follow the Netscape cookie specification:

<http://devedge.netscap e.com/library/manuals/2000/javascript/1.3/reference/cookies.html#10 02170>

Some UAs set cookies only if set by a resource retrieved via HTTP, thus
they do not set it with documents accessed with "file:" URIs, for example.
Some UAs consider cookies without "domain=" invalid and will not set those.

Possibly.

I found it best to always set the date and time in IE. Figure out how
long you need to use the cookie and add a reasonable about of extra time
like an hour.

Has anyone gotten sessions cookies to work in IE: that is a cookie set
in IE without the date/time?

Which browsers do not understand new Date("December 31, 2050"); ?

It is non-ISO numeric date strings that are unreliable; but "2050/12/31"
should be safe everywhere, and is understandable by anybody; whereas
some people think that December needs a Zed, or possibly a Zee, or
transpose letters in it.

In this case, "01/01/2051" could have been used.
