Hi,
I assume you have two installations (web projects) of Kentico
CMS. One is staging and second one is production.
In this case you can setup the IIS for these folders to have two separate web sites or web applications. One application/site can run under localhost and the other one under 127.0.0.1. Or, you can also setup the web site to run in subfolders, e.g. localhost/production and localhost/staging
Best regards,
