The commercial web hosting company now supports my application with a server farm. The link, above, discusses a problem a security fix introduced and how to fix the problem. It seems there is a mechanism by which variables in the application are persisted by putting them in a package and sending the package back and forth between the browser and the server. In a server farm, as load increases, it is possible for one web session to be handled by more than one server. The security fix assumes all interaction will occur on a particular server. When it does not occur on a particular server the end user's interaction becomes unsatisfactory. The package and the server are lashed together with a MAC address. When the MAC address changes, as it would when the load master moves the session to a different server, there is a malfunction. The Microsoft solution is to specify the MAC address in Web.config. That way the application provides the MAC address, not the hardware on which the application is running. I followed directions and generated the XML (PowerShell) that goes into the Web.config file and put the XML where I was told to put it. After that the application refused to run. Presumably there is a syntax error in Web.config. Do you have any idea what is wrong with this Web.config file? Thanks.
