Making a subdirectory redirect to another file

I am working on an instant messaging application for android. I want to create a webpage which redirects the user to a profile inside the application. So if the user opens "http://ift.tt/2enOs5G", it will redirect him to another page sending the "Name" as an argument. The application handles opening the profile and showing it. I have got the application working but am unsure how to make the redirecting to work. The Name changes according to the user. What is the best to way to redirect without making multiple directories for each user? Thanks in advanced, Aditya
