I have a situation where domain.com (is the live server - A record points to this server). We have another domain.com (which is the test server - users manually set hosts file).
Users would like to access the live and test sites simultaneously on the the browser. What is the best way to do this? Users use their PCs/Macs to view the site.
I know that if you set the Hosts file setting on the PC then you can decide which IP to use that works but then switching hosts file each time is pretty hard to do.
