Guys, I'm really new with server administration... i'm an ordinary web developer, but i found this pc with uniform server 2.6 working, and i just want to find out how you can create a subdomain. I've googled on the Internet, and it's just quite a pain browsing into the results.. and i saw that luckily there's a forum exclusively for this webserver type... so is there any step-by-step procedure on how to create a subdomain using Uniform Server 2.6... Thanks in advance!
