• I'm looking to configure my website so that anything.mydomain.com will land the visitor on my site (mydomain.com), i.e., bob.mydomain.com or trucks.mydomain.com.  How do I do this?

• For Plesk users:
  • pending update...
• For cPanel users:
  • Simply add a subdomain like you would any other subdomain in the cPanel interface, except make your subdomain * (as if to show on the screen: *.example.com), and leave the document root field empty... cpanel will automatically populate it with your domain's website root, which will look like this, after you save the change:

Note that our example here also shows another subdomain (called "othersubdomain"), which is configured to point to a subfolder... so with this configuration:

• anything.mydomain.com will serve the same content as mydomain.com and www.mydomain.com, the files in /public_html
• othersubdomain.mydomain.com will serve the content that's stored in /public_html/othersubdomain
