Caching Patterns in ASP.NET

Question

So I just fixed a bug in a framework I\'m developing. The pseudo-pseudocode looks like this:

myoldObject = new MyObject { someValue = \"old value\" };
cache.Inse

Dirty tracking is the normal way to handle this, I think. Something like:

class MyObject {
  public string SomeValue { 
     get { return _someValue; }
     set { 
       if (value != SomeValue) {
          IsDirty = true;
          _someValue = value;
       }
  }

  public bool IsDirty {
     get;
     private set;
  }

  void SaveToDatabase() {
     base.SaveToDatabase(); 
     IsDirty = false;
  }
}

myoldObject = new MyObject { someValue = "old value" };
cache.Insert("myObjectKey", myoldObject);
myNewObject = cache.Get("myObjectKey");
myNewObject.someValue = "new value";
if(myNewObject.IsDirty)
   myNewObject.SaveToDatabase();
