I can't remove cookies using JS and they don't seem to expire.

Reproducible: Always
Steps to Reproduce:
1.Put this code anywhere document.cookie = '';
2.
3.

Actual Results:  Does nothing.

Expected Results:  Should remove all cookies which match domain and path.

document.cookie = ''; // removes cookies when I call it with Netscape 4.x or 
IE - M18 doesn't do anything here

I also tried using Perl:

print "Set-Cookie: \n";
# or print "Set-Cookie:\n";

This one creates a cookie with name and value set to an empty string.

They also don't seem to expire when I say:

$c->expires('-1d') # yesterday

I'm afraid I don't understand this bug report at all.  Could you try explaining 
it so it's a bit clearer.  Thanks.

Let me try it with a question. What should browser do when I say:

document.cookie = '';

I assume that the "I" you refer to is not a person but rather is javascript 
contained on a web page that the browser encounters.  ;-)

In that case it sets a cookie with no expiration time.  If you want it to expire 
at the end of the session you would add an ";expires=0" and if you wanted it to 
expire at some particular time in the future you would insert that time/date in 
place of the 0.

If you want to remove a cookie, you need to set a new cookie with the same name 
and give it an expiration time that has already passed.

This is the same behavior as in 4.x, so if you are saying that 4.x acted 
differenlty, please give a concrete example with step-by-step details.
