Domain Pointing is the process of setting & redirecting multiple or a single domain to your primary domain or pointing one domain to another. It can be deployed to point a domain to a specific directory or folder of another domain/site. For example, pointing http://domainname.com to http://exampledomain.com/testpage/ . Here domainname.com can be seen pointing to /testpage directory of http://exampledomain.com.
Domain Pointing helps in maintaining two dissimilar and different web sites within a single hosting account thereby reducing the hosting charges.
