Creating cookies in php

[Anon]

I am using a Netscape browser (4.73). I have created a cookie in my
php program with the following code:

setcookie("Session_Key", "Test_Value",28880,"/cgi-bin2","",0);

When I try to access the cookie via $Session_Key then nothing is
returned. If I try to do the same test using Internet Explorer (5.0)
then I get the proper value for the cookie.

Is there a restriction with creating cookies in php and accessing them
using a Netscape browser? All ideas will be greatly appreciated

I have heard that you need to fill out all items of the cookie thing, which you seem to do?

Strange thing is, correct me if I'm wrong, but is 28880 not in the past?
