Hello Adam,

You can add the reference DLL's in a comment line at the top of the script. For MySQL you can use the standard ODBC library of dotNET like this:

// AddReference System.Data.dll

using System.Data;
using System.Data.Odbc;

In the Scripting Pack that you can download from the download page of this website you can find an example of a script that uses the ODBC library. This script is called '\ConnectorScripts\DatabaseQuery\ODBCKeywordLookup.cs'. It is meant for the Scripting Connector and won't work for the HTTP callbacks but the reference DLL calls are the same.

If you use an external database in the C# Http CallBack Script, you'll have to make sure that the database calls are fast enough. The gateway or connector is blocked during the database call and if the database transactions are slow it will have a negative effect on the performance of the gateway or connector.
