HTTP statuscode to retry same request

Question

Is there an HTTP status code to instruct a client to perform the same request again?

Use the 307 redirect, but add a retry counter:

http://path/to/server?retry=3

This will make the URL different on each retry, preventing loop detection. And the server could check for retry hitting a limit, and abort with an error when that happens, so the user doesn't wait forever.
