Hi

How can I create a session cookie ? I want to create a cookie in browser's
memory that automatically expires when I close/exit the browser. A need also
to know how can I access that cookie.

Thanks in advance for your help

Have my cookie functions.

/* This file contains cookie functions. */
/* File Functions:
1. setCookie - writes cookie
2. getCookie - gets value of cookie
3. removeCookie - deletes a cookie
4. detectCookies - checks if cookies are enabled
*/

function setCookie(cooki eName, cookieValue, expireDate)
{
/* Pass in three strings - the name of the cookie, the value, and the
expire date.
Pass in a "" empty string for expireDate to set a session cookie
(no expires date).
Pass in any other date for expire as a number of days to be added
to today's date. */

if (expireDate == "")
{
expires = "";
}
else
{
expires = new Date();
expires.setDate (expires.getDat e() + expireDate);
expires = expires.toGMTSt ring();
}
document.cookie = cookieName+"="+ cookieValue+";e xpires="+expire s;
}

function removeCookie (cookieName)
{
/* Pass in the name of the cookie as a string and it will be removed.
*/
expires = Now();
document.cookie = cookieName+"= ;expires="+expi res.toGMTString ();
}

function getCookie (cookieName)
{
cookieValue = ""
if (document.cooki e.indexOf(cooki eName) == -1)
{
// there is no cookie by this name for this user
return cookieValue;
}
else
{
// get the beginning index of the cookie by looking for the cookie
name
cookieStart = document.cookie .indexOf(cookie Name);
// get the beginning index of the cookie value by looking for the
equal sign after the name
cookieValStart = (document.cooki e.indexOf("=", cookieStart) + 1);
// get the end index of the cookie value by looking for the semi-
colon after the value
cookieValEnd = document.cookie .indexOf(";", cookieStart);
// if no semi-colon, then use the whole length
if (cookieValEnd == -1)
{
cookieValEnd = document.cookie .length
}
// use substring to get the text between the two indices and that
is the value of the cookie
cookieValue = document.cookie .substring(cook ieValStart,
cookieValEnd);
return cookieValue;
}
}

function detectCookies()
{
/* function returns true if cookies are enables, false if not */
setCookie("test ", "test", "");
tmp = getCookie("test ")
if (tmp != "test")
{
return false;
}
else
{
return true;
}
}
