javascript - How to Delete Session Cookie?

Question

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.

A session cookie is just a normal cookie without an expiration date. Those are handled by the browser to be valid until the window is closed or program is quit.

But if the cookie is a httpOnly cookie (a cookie with the httpOnly parameter set), you cannot read, change or delete it from outside of HTTP (meaning it must be changed on the server).
