Invisible cookies with Javascript for IE 6

[Wolfgang Adamec]

Hello everybody!
I had no experience with cookies up to today.
I read about the properties of cookies. Then I started to write
a few lines of Javascript into my html-page:

function SetMyValue(name , val)
{
document.cookie = name+"="+val;
}

and

SetMyValue('fir stname','michae l');

I did not set the properties "expires" and "domain".

When I put the page to my server, called it with the IE 6 and looked
into the IE for my cookie, it was not there. But when I made a cgi program
that showed HTTP_COOKIE, I saw, that the IE was sending it. So I had
an invisible cookie with my IE. Only when closed the IE and opened it again,
it was lost.
Strange thing!

I suggest using an existing set of cookie routines. The document.cookie
can contain existing cookies and you need to preserve them. ( Don't know
why such routines aren't shipped with the browsers. )


~kaeli~ has developed some cookie code. You may view it in this article:

Also, ~kaeli~ reports that:
There's some even better code that sets more cookie properties like
domain, secure, path, etc here.

This code will preserve existing cookies. The cookie property is "magical"
in the sense that it doesn't act like a normal object property. Assigning
such a string, preferably with host/path/expiration information as well,
will only add one cookie to the set that exists. Reading it back will
generate a string containing all cookies, with no expiration information.

Try this code:
---
document.cookie = "hello=worl d";
document.cookie = "world=now" ;
alert(document. cookie);

How true. Indeed the cookie code I use uses a regular assignment.

How do you want the cookie to work?

Without giving the date, the cookie expires when the session goes
away.

I have had a bit of trouble with cookies with IE when I didn't specify
the date. The cookie would disappear on me. I found it necessary to
provide a date
