Nested URL in Golang : I'm totally new to Golang I started like tomorrow. So What I want to achieve is routes like

`user/profile`

`user/cart`

`user/products`

Currently, I'm doing this

```
r.HandleFunc("user/signup", signupHandler).Methods("POST")
r.HandleFunc("user/signin", signinHandler).Methods("POST")
r.HandleFunc("user/profile", profileHandler).Methods("GET")
r.HandleFunc("user/cart", cartHandler).Methods("POST")
r.HandleFunc("user/products", productsHandler).Methods("GET")
```

As you can see these routes starts with `user` so can how can I know it's a `user` routes so I can send handle it in a different file.

I want something like

```
r.HandleFunc("user/", handlerWhichHandelAllTheRequestFromUser)
```
It should handle all the URL which starts from `users`.

P.S I'm using mux
