ConfigurationSettings.AppSettings[key]

Mar 17 2008 6:29 AM

i get an error when i try to access a web service.
The webservice is internally developed by another developer who has left. The website uses 'Sitecore' to render
its pages through a subscription model.
Therefore a cookie is passed to the webservice to access the value of the appsettings to retrieve the data.

I am not able to access the value of the appsettings 'key'. Please look at 'somestring' in the webconfig file.
A string 'xxxxxx' is passed to cookie to verify. Also it looks like only safe addresses will be authenciated in the config file.

Below are:
1. the code im executing.
2. the error page.
3. The app.config file

Please advise as to how i could retrieve the 'key'.
