This question already has an answer here:
Various questions have come close to this but involve using a browser extension or proxy server or only block the domain and are not questions or answers about leaving a domain unblocked while only blocking access to a specific page on that domain.
But I'm not asking how to:
1) use a proxy (because I use opendns already),
2) use a browser extension (because I need it to work on all browsers),
3) block a whole domain,
But I must only block access to only a specific page on a domain such as
www.example.com/page. and can not use proxies or extensions because I need a solution for a whole business network. This is not just my home computer I'm talking about here.
Unlike some of the questions linked above, I need to specifically block only certain pages on a webpage, and I don't want to block the entire domain or use a browser extension.
