No login/logout redirect

[prowarfare]

I would like a code where if you put it on any page, it will just log you out and stay on the page you were on and not redirect you any wear.

Also when you login it will just log you in and stay on the page you are on and not go to the login redirect page.

This will be very helpful as I am creating a website which will have onsite login and logout.

I am also using this for the mobile version of my website which having many redirects becomes a big data hog.

It would be best if someone could create the code where you designate where you go after login in or out.
