Maybe my topic title isn't correct but here's what I want to achieve (and perhaps best if I use the real example):
I have numerous sites hosted on a server, with a primary domain pointing to a particular folder. I have just registered a second domain and wish to point that domain to a new site's folder (which I've done using cPanel).
However, whenever a user calls up the new domain name, I want the browser to display the URL of the new domain only, i.e. not to show the full URL (which includes sub folder and primary domain).
Actual WordPress installation:
http://www.splashworxmultimedia.com.au/metalwordpress/
New sub domain: http://www.heavymetaldiary.com
Which points to the directory above. However I want the new sub domain to display in the browser address bar only, not the actual URL and sub folder.
Example: http://www.heavymetaldiary.com/my-blog-post/
instead of: http://www.splashworxmultimedia.com.au/metalwordpress/my-blog-post
I've read about Apache's mod_rewrite but don't see reference to what I'm trying to achieve.
Any thoughts? This must be a common issue for multiple installations..?
