One website is blocked by ISP, but it has several working aliases. So, when found links like http://site1/article I can type http://site2/article and it works. However, a static DNS entry for site1 doesn’t solve the issue because site2 refuses requests using IP-address only. The URL should start with “site2”.
I can make a redirector web application for this case and make a static DNS entry to the PC hosting this web app, but how to do the redirecting job automatically with RouterOS only? Web Proxy?
