Ok so I am in the works of experimenting with a website that uses keys from the web.config file. If a value is changed somewhere when running the application, the web.config file is altered at the <add key = "variablename" value = "whatever" />. It seems to run fine in the compiler and all of the variables are cahsnged over a s necessary but when I upload it and run it on the server it does not want to load properly. I am working on an error page to support the stack trace but I am curious. Can you edit the web.config file while runining a web application on a server or will it contiunue to throw an error no matter what I do?
