$PHP_AUTH_USER & $PHP_AUTH_PW Question.

Hello folks,

Does anybody know how to get rid of $PHP_AUTH_USER and $PHP_AUTH_PW
variables without closing the browser?

I am making the authorization with headers which forces the browser to pop
up the authorization dialog. After the successful authorization the page
displays somewhere a link "log out" which points to a script "logout.php".

I tried to unset $PHP_AUTH_USER and $PHP_AUTH_PW in "logout.php" but it
doesn't work. When I want to relogin, the browser doesn't pop up the
authorization dialog, and enters the site with the old authorization values.
So I must first close the browser and after that to reenter the site.

How can I do it without closing the browser ?

Any help appreciated.
Thanks in advance.
