Is it possible for customize squid to temporary allow blacklisted website via the error page?
Similar to Webwasher functionality below where it can detect blacklisted website, show an error page with a green button which the user can click to have 30 minutes allowance to visit that website.
translation: Access to the desired site requires your confirmation. Your selected internet site "http://www.amazon.com/" belongs to the category (Online shopping at). If access is business-related or held outside of working hours, please confirm this by clicking on the "confirmation" If the page longer than 30 minutes is selected, this message appears again. Thank you for your understanding.
