Sorry to reopen a very old thread, but I am experiencing the exact same thing in Ready! API 1.9.0
I use ready-api to call the server, where I have a debugger running, and after a 10-20 seconds the debugger intercepts another call, with the exact same content, originating from ready-api.
This is very annoying, because the debugger doesn't always handle this properly, and if the call has side-effects, a second identical call can mess up my test-result.
I have been looking hard for a "do not retry" or "number of retries: 0" setting. Is this still not possible, or am I just looking in the wrong places?
