home page cache

[Shxuuer]

I know Vercel official server has cache about six hour or even more. When i wait for one day, result of http server is updated, but readme of home page didn't update. After checking the request url of readme stat, it direct to
https://camo.githubusercontent.com/
rather than
https://github-readme-stats.vercel.app/

I know github has another cache, and I want to know when github update resources cached.

I hope I have expressed my meaning clearly
