To set up a subdomain:
This can be, for example, a topic of your site, organization department, or any other combination of letters, numbers and hyphens (up to 63 characters in length). The subdomain name must begin with an alphabet character. Subdomain names are case insensitive.
Then, the SSL certificate installed under the parent domain will be used for encrypting transactions. By default, when you publish the site, you need to upload the web content that should be accessible via secure connections to the
httpsdocs directory, and the content that should be accessible via plain HTTP, to the
httpdocs directory. For your convenience, you can choose to publish all content through a single location –
httpdocs directory. To do this, select the option Use a single directory for housing SSL and non-SSL content.
When the specified limit is exceeded, you will not be able to add files to the web space, and editing existing files may corrupt them.
Otherwise, your web site may not function properly. For example, if your web site is written mainly in ASP and uses some applications written in PHP, such as those from the Application Vault, select the ASP support and PHP support check boxes.
It may take up to 48 hours for the information on new subdomain to spread in the Domain Name System and become available to the Internet users.
To publish web content to the subdomain's web space, follow the instruction presented in the Creating and Publishing Your Site section.
