Answer 1

It's intended behavior, and is configurable. By default, Gorilla mux will do path cleaning, i.e. removing double slash etc. for new router. You can left the double slash as is by:

router.SkipClean(true)

The SkipClean documentation says:

...
When true, if the route path is "/path//to", it will remain with the double slash. This is helpful if you have a route like: /fetch/http://xkcd.com/534/
