SPWebConfigModification Class : Holds modifications that are made to the web.config. Following example helps you to add the safe control entry on feature activation. public override void FeatureActivated( SPFeatureReceiverProperties properties)         {             try             {                 SPWebService contentService = SPWebService .ContentService;                 contentService.WebConfigModifications.Add(GetConfigModification());                 // Serialize the web application state and propagate changes across the farm.                 contentService.Update();                 // Save web.config changes.                 contentService.ApplyWebConfigModifications();             }             catch ( Exception e)             {                 Console .WriteLine(e.ToString());                 throw ;             }         }         public override void FeatureDeactivating( SPFeatureReceiverProperties properties)        

AllowUnsafeUpdates is a property of SPSite SPWeb If user do't have any permission to update the data. So we run the code with special permission for that we use RunWithElevatedPrivileges block, by using this code user update the item on the behalf of system account, for that we need to  Set AllowUnsafeUpdates   to true to disable security validation on Update(). This is request if persisting anything within RunWithElevatedPrivileges. Any exception, handled or otherwise, sets AllowUnsafeUpdates to False.
