How to dynamically, via javascript, delete a session cookie, without manually restarting the browser?
I read somewhere that session cookie is retained in browser memory and will be removed when the browser is closed.
// sessionFooCookie is session cookie
// this code does not delete the cookie while the browser is still on
jQuery.cookie('sessionFooCookie', null);
Thanks.
More Info: The code snippet above is a javascript code snippet, using jQuery and its jQuery.cookie plugin.

Be sure to supply the exact same path as when you set it, i.e.
Setting:
$.cookie('foo','bar', {path: '/'});
Removing:
$.cookie('foo', null, {path: '/'});
Note that
$.cookie('foo', null);
will NOT work, since it is actually not the same cookie.
Hope that helps. The same goes for the other options in the hash
you can do this by setting the date of expiry to yesterday.
My new set of posts about cookies in JavaScript could help you.

This needs to be done on the server-side, where the cookie was issued.
Deleting a jQuery cookie:
$(function() {
var COOKIE_NAME = 'test_cookie';
var options = { path: '/', expires: 10 };
$.cookie(COOKIE_NAME, 'test', options); // sets the cookie
console.log( $.cookie( COOKIE_NAME)); // check the value // returns test
$.cookie(COOKIE_NAME, null, options); // deletes the cookie
console.log( $.cookie( COOKIE_NAME)); // check the value // returns null
});
There are known issues with IE and Opera not removing session cookies when setting the expire date to the past (which is what the jQuery cookie plugin does)
This works fine in Safari and Mozilla/FireFox.
