There is no MD5 or cookies involved. As already pointed out it is
base64 only and it gets sent by the browser on every request.

> Yes you're right, the password is sent to the server in plain text. But isn't the password just send only ONCE (when you log in)? Or is it stored inside a cookie and send with every request? Because the "get_basic_auth_pw()" can receive the password for every single request (not just the first one). That's why I thought it get's the data from the auth file...

> The whole procedure I was thinking about is the following:
> 1. user provides login & pw (login screen)
> 2. data is sent to the client
> 3. pw is MD5 encrypted by apache and matched with the already encrypted pw inside the auth file
> 4. get_basic_auth_pw() reads the pw from the auth file
>
> But that's not the case as it seems... Only other way I can imagine is the use of a cookie for resending the password with every request. But that's rather stupid imo... =)
