How to understand the sentence that the get request is harmless when the browser rollback

I saw this sentence in an article that introduced the difference between get requests and post requests.
does the so-called harmless mean that the browser will cache this request and no longer send the request when it falls back?

means that from the definition of method , get is idempotent, and how many times it is executed does not affect the final stored result. And post creates a new resource with each call.


get puts the request parameters in the url of the request, and the fallback operation actually takes the result from the previous cache
