Important Note: If you aren't using gorilla/mux, you need to wrap your handlers with 
context.ClearHandler or else you will leak memory! An easy way to do this is to wrap the top-level mux when calling http.ListenAndServe:

http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
The ClearHandler function is provided by the gorilla/context package.

More examples are available on the Gorilla website.
