Cache Algorithm

For an integer value:

private int GetInteger(int uniqueID)
{
    int integerv;

    string key = String.Format("{0}_{1}", "SOMETHING", uniqueID);

    object value = Cache.Get(key); // could be HttpContext.Current.Cache.Get

    if (value != null) {
        integerv = (int)value;
    }
    else {
        integerv = _db.GetValueFromDb(uniqueID);
        Cache.Add(key, integerv); // could be HttpContext.Current.Cache.Add
    }

    return integerv;
}
