OPC Server Access from ASP.NET applications ?

In ASP.NET application we recommend using the XMLDA.NET client component. Web applications have a different lifetime behavior than DCOM based OPC servers. DCOM have a permanent connection and the clients have to connect/disconnect. Web applications are stateless and basically each access is independent of others. XMLDA.NET takes care of these differences and automatically connects/disconnects the OPC DA server.
