It's best to modify the avatar URL after the avatar changes.

If you want the URL to be the same, remember to take it with you when ?r=xxx you request it, and remember that it is xxx randomly generated by the server or client each time.

Another approach, such as Facebook, uses a fixed URL for a user's avatar, but when actually accessing the URL, it generates a 302 jump to the real image address, which guarantees that each avatar is different.
