While using my REST service, i have this error when trying to use it

Access to XMLHttpRequest at 'http://cloud1.acut.it:8090/do.acr?cmd=newsession' from origin 'http://localhost:9000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

If i test my REST on some online tools i have no problem, with others it doesn't work

Suggests?

Thanks

Anything generated from another browser and going across domains requires CORS which is a browser HTTP client policy tool that checks for the CORS policy. If you're testing from a non-browser tool (like WebSurge or Postman) then CORS isn't required because it's not a browser doing the request.

You can add CORS support in your process class and OnProcessInit():
