a web proxy server instead of IP mask

I resell sms and i subscribe from a company. now my company gave me an ip to mask, so i can give my customers,to pass their parameters: like ## Deliverables [login to view URL] now if a customer types in? [login to view URL] they are redirected to my host, this i dont want, is there a way a proxy class can be created so that when anybody comes here? [login to view URL] they will not see my host,like a proxy class or something, to prevent this page from opening if they type? http://mytest.smslift.com.
