Here is the situation: We have an affiliate program where affiliates send trafic to our websites using URLs such as [login to view URL] The problem we have is that all affiliates links appear as different pages in search engines such as the example beow: [login to view URL] [[login to view URL]][1] [[login to view URL]][2] We need a script to redirect? humans to the affiliate script (so affiliates commissions are tracked)? and bots to the website homepage, using a proper 301 redirect. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
