is there a way to detect if a user is using a proxy server to visit my website? i am looking at my analytics statistics and there are some urls with proxy server. so when i visit on these urls, it shows my website, but the proxy servers also embed their own ads, which is not fair because they are making money ouot of my own content so want to be able to check if the user came with from a proxy website and if so, i want to redirect them to my own website instead that way it will not show their ads

can that be done?
