[squid-users] Change of authorization request

Hi,

I'm using proxy_auth so that users can't get into the internet without a
 valid library account. Now, I need a way, to change the browsers log-in
screen so that an additional disclaimer and explanation can appear.
Is this possible?

Thanks in advance,
Daniela
