-   method unless it has some means to know that the request semantics are
-   actually idempotent, regardless of the method, or some means to detect that
-   the original request was never applied. For example, a user agent that
-   knows (through design or configuration) that a POST request to a given
-   resource is safe can repeat that request automatically.
-   Likewise, a user agent designed specifically to operate on a version
-   control repository might be able to recover from partial failure conditions
-   by checking the target resource revision(s) after a failed connection,
-   reverting or fixing any changes that were partially applied, and then
-   automatically retrying the requests that failed.
