Most people never give much thought to URL structure, but it’s important to understand the basics to learn how a Wildcard SSL works. This is a URL:
- Domain – This is the host name for the website. As long as you can identify the domain you’ll know what website you’re on.
- Top-Level Domain – The portion at the root of the URL indicates either the country of origin or a generic top-level domain (.com, .org, .edu)
- Page – This is the path of the specific page you’re on.
- Sub-Domain – Located in front of the Domain, a sub-domain is a part of the site that can host its own apps or services. For example, www.domain.com and blog.domain.com are separate subdomains.
