How to Add or Remove "www" in Incoming Requests?
Even if the DNS records exist, your backend service may not accept the "www" subdomain in the incoming request, or it may be configured to accept the "www" subdomain even if it's not present in the DNS records. With an action defined on the TR7 ASP, the "www" subdomain information can be added or removed from requests.
Warning
In this article, "Set HTTP Header" Action is explained for subdomain manipulation. Similarly, "Location Redirection" Action can also be used for subdomain manipulation, allowing the addition or removal of the "www" subdomain.
