+ | The technique used to access the remote system is a JavaScript-based creation of a HTTP-Get request or an automated submitting of an HTML form (HTTP-Post). Each system code given in $n corresponds to a particular request algorithm within the CT web interface. Therefore codes other than on the List of System Query Codes must not be used without prior consultation with the Data Conversion Group. | ||
