New Uploading Error

I just recently got all my uploading issues resolved (I thought).  Just recently when uploading a file or files I get the following error:
"The connection has been closed between the browser and the server."

.NET reports the following

Inner Exception Type: System.Web.HttpExceptionInner Exception: An unhandled exception occured in the upload module.Inner Source: GleamTech.Web.FileTransferInner Stack Trace:
at GleamTech.Web.FileTransfer.UploadHttpModule.OnPreRequestHandlerExecute(Object sender, EventArgs e)
   at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Your immediate help is much appreciated.

This appears to be an IIS7 issue and integrated mode.
I already have the recommended settings in my web.config to run this in integrated mode.

Please see SharePoint 2007 File Upload error and Upload working when debugging but not in IIS. Let me know if these are not the case.

I've searched all the forum posts for answers and have found none.  The ones you refered to - I've tried without success.
I seem to have all the proper web.config info.  The only thing I can think of is that there is something else in the web config that is cause interference, but don't have many ideas.

I will let you know if we can find a possible cause by the help of the feedback from other customers.

In the meantime, I recommend you to change FileVista's application pool to Classic .NET AppPool in IIS. If you don't get the error under classic pipeline mode, then it does not matter for FileVista because it can run under both modes.

Running in Classic Mode is not an option for us at this time.
Would it help if I send you our web.config file?
Thanks,
Cory

Ok send me your web.config and I will examine it.

I see that you are using Forms Authentication so that should be causing the issue. Please see Upload with Forms Authentication for the solution.
