  "answer": "The `Router.ServeHTTP` method is defined in `mux.go` at lines 188-229. It dispatches the handler registered in the matched route and allows retrieval of route variables using `mux.Vars(request)`.\n\nHere is the signature:\n```go\nfunc (r *Router) ServeHTTP(w http.ResponseWriter, req *http.Request)\n```\n\nAdditionally, there is a `customMethodNotAllowedHandler.ServeHTTP` method defined in `mux_test.go` at lines 2893-2896, which is a custom handler for method not allowed responses."
