Function wrapMiddleware

modules/caddyhttp/routes.go:331–341

wrapMiddleware wraps mh such that it can be correctly appended to a list of middleware in preparation for compiling into a handler chain.

(ctx caddy.Context, mh MiddlewareHandler)

// appended to a list of middleware in preparation for
// compiling into a handler chain.
func wrapMiddleware(ctx caddy.Context, mh MiddlewareHandler) Middleware {
	return func(next Handler) Handler {
		return HandlerFunc(func(w http.ResponseWriter, r *http.Request) error {
			// EXPERIMENTAL: Trace each module that gets invoked
			if server, ok := r.Context().Value(ServerCtxKey).(*Server); ok && server != nil {
				server.logTrace(mh)
			}
			return mh.ServeHTTP(w, r, next)
		})
	}
