If I use http.Redirect in a middleware, do I explicitly have to return after the http.Redirect before calling next.ServeHTTP(w, r)?
If I have something like this, do I have to return explicitly after every http.Redirect in order for the code to stop executing after the redirect? What happens if I don't return?
// HTTPSNonWWWRedirect redirects http requests to https non www.
func HTTPSNonWWWRedirect(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
if r.TLS == nil {
u := *r.URL
u.Scheme = "https"
if r.Host[:3] == "www" {
u.Host = r.Host[4:]
http.Redirect(w, r, u.String(), http.StatusMovedPermanently)
return
}
http.Redirect(w, r, u.String(), http.StatusMovedPermanently)
return
}
next.ServeHTTP(w, r)
})
}
