How to reset $_SERVER variable ?

[IndraDev]

Hi,,
I've used protocol authentication on my web site, however I've got a retardant however do I reset that $_SERVER['PHP_AUTH_pw'];
Variable? thus it once more can enkindle authentication ?

I have never tried to make this kind of authentication myself... but isn't it the usual unset()?

like this?

if (isset($_SERVER['PHP_AUTH_PW'])) {
unset($_SERVER['PHP_AUTH_PW']);
}

alternatively, just set the value to null?
