HTTP Authentication Options

For the Login URI and Logout URI options, you can use the following variables to support your installation:

%host% - The current value of $_SERVER['HTTP_HOST']
%base% - The base domain URL (everything before the path)
%site% - The WordPress home URI
%redirect% - The return URI provided by WordPress

You can also use %host_encoded%, %site_encoded%, and %redirect_encoded% for URL-encoded values.
