Preflights are cached, but because CORS is per-URL caching can be of limited value. If your API uses `/info` and `/edit`, a preflight request has to be made for both (assuming a preflight is necessary). If your application has dynamic URLs (e.g. `/widget/1`, `/widget/2`, etc.) the problem is exacerbated even further. |
