I am now running my large (350+ screens, 120+ tables) FoxPro 9.0 app on AWS Windows server 2016 running ThinfinityUI. Thinfinity hosts my app unchanged on the server and it looks to the end user as though it's a normal web app. I need a way for my VFP APP to read the parameters sent with the URL. Is there a West Wind product or any method anyone knows of that can read the parameters?

I'm not sure if I understand your question correctly, but it sounds like you need a Web Server and to run a FoxPro application in front of it?

We provide West Wind Web Connection which lets you use FoxPro to handle Web requests.

The only way to 'read parameters' sent to a Web Server is to host a Web server and capture the data as part of a Web application. There are a number of ways to do this, but if you want to use FoxPro to do it then Web Connection is a good choice.

With Web Connection you can use Window's built-in IIS Web Server or a standalone .NET Core based Web Server we provide in the box. The latter can be a good choice for intranet applications where you just need to host a server on a local network.

Other alternatives - especially for one offs are - using a basic Web framework like ASP.NET or NodeJs on a server and use ODBC/OleDb to access FoxPro data. For one offs this can be easier because it doesn't require you to actually run FoxPro on the server which requires a more special setup and configuration isn't readily available on your typical Web host provider.

You'll need to be more specific of what you want to do for more info.

Thinfinity displays your VFP UI in a browser, but your VFP app runs within some kind of app container black box, not sure you have the ability to run some code of your VFP app in response to a parameterized web request.

FoxInCloud does that, at the expense of some code adaptations, and with a cheaper license per concurrent user.
