Editing Web Apps (section)

==Connecting Domains==

Anyone can add a connection using the "UpdateDNSZone" command.  

In general, the command will contain one or more of the following elements:

* An X-ALIAS-<RR> record: this will copy the relevant DNS settings from a reference zone to the desired zone set in the command. It will also delete any resource records of the same type for the specified DNS zone (e.g. for your root domain). Your zone will be automatically updated accordingly if there are any changes to the reference zone. You can learn more about the X-ALIAS-<RR> system (alias xDNS record sets) [https://wiki.hexonet.net/wiki/XDNS:X_ALIAS_RR here]. 

* Custom resource record(s): these will be specific to the web app, and may or may not differ for each customer using that web app. For example, a web app provider may specify a random CNAME host/destination to be used by a customer when connecting their domain. 

* A redirect record: this will redirect the 'www' site to the root domain. E.g. http://www.mydomain.com will resolve to http://mydomain.com.

* Deletion of resource records: this will delete existing X-ALIAS-<RR> record(s), removing any existing web apps utilizing the same type of resource records.
