This is actual Web architecture and not a remote desktop approach such as Citrix. So yes, the Excel and DLLs run on the individual client machines where the web browser is.

Sorry for my ignorance Armeen, but I would have though that default browser security models would prevent calls out to the Excel and DLLs. I appreciate that you can dumb down the browser security to do this, but can you be specific about only the Appeon stuff being able to do this and not other sites?



I'm always worrying about the security implications and my support manager is always difficult about deployment limitations.



Thanks in advance for helping my education. :)

PowerServer Web uses a browser plug-in. So it's not that it lowers the browser security... other web apps would not be able to make a call out. But PowerServer Web apps can utilize the PowerServer-specific plugin to make calls out. The architecture is really no different than what a traditional PowerBuilder app can do. If you do need HTML solution, then we would suggest to rewrite the UI as ASP.NET Core pages and migrate the PowerBuilder business logic to C# using the new .NET DataStore of PB 2019 and the DataWindow migration utility.
