SharePoint 2007 File Upload error

We have installed a FileVistaControl control on an ASPX page in the SharePoint LAYOUTS folder.

The control is displayed on an ASPX page that runs in the contect of SharePoint 2007.

Everything works correctly except the file upload which fails after a couple of seconds with the following error message:

An error occurred:
The connections has been closed between the browser and the server.

Any ideas?

1. All FileVistaControl assemblies must be strongly typed.

2. The following tag must be the first entry in the <httpModules> section in the SharePoint web.config.
Do not include this tag in the local web.config.

<add name="GleamTech.Web.FileTransfer.UploadHttpModule"
               type="GleamTech.Web.FileTransfer.UploadHttpModule, GleamTech.Web.FileTransfer, 
          Version=1.0.3042.30619, Culture=neutral, 
          PublicKeyToken=71e2ej9e8ko872"/>

Derek,
Thank you very much for the feedback on SharePoint integration, I think other developers will find this information very useful.
