Hi,
I just noticed that using a space int the auth realm breaks the proxy.
it's quit simple just use the name "Please Auth" and it will break.
:: Starting reverseproxy
AH00526: Syntax error on line 17 of /usr/apache/conf/reverseproxy.conf:
AuthFormLoginRequiredLocation takes one argument, If set, redirect the browser to this URL rather than return 401 Not Authorized.
the config file at this location shows a clear error.
