>If you are creating the request why not just set the UserAgent property yourself ?

The request is creating from:

Public Class WebForm
	Inherits System.Web.UI.Page

	Public oProcess As LXProcess = New LXProcess()
		oProcess.oRequest = Request

End Class

Public Class LXProcess

    Public oRequest As System.Web.HttpRequest

End Class

So, basically, this is the standard page request object. I believe this is the proper way to set it.
