Caching Mechanism and Its Expirations ASP.net cache or AppFabric Caching are ways to  increase the performance of the web application by r educing server round trips to database. However the validity of the cached data needs to be ensured, to enforce this, we have the following options 1. Dependency Mechanisms:      Files, SQL Cache Dependency etc This ensures that the cache is re-validated or refreshed once a dependent has changed or been altered 2.  Expire Cache:      The cache will expire after a time frame and the newer items will be added to cache when ever accessed or processed after expiry.  In Cache Expiry, we have the following options 1. Absolute Expiration:   Absolute expiration means It will expire cache after some time period set at the time of activating cache. This will be absolute expiration whether cache will be used or not It will expire the cache. This type of expiration used to  cache data which are not frequently changing. 2. Sliding Expiration:

In order to compare strings for their equivalence, we have to follow this Rule from Microsoft " When you specify either  StringComparison.Ordinal  or  StringComparison.OrdinalIgnoreCase , the string comparison will be nonlinguistic. That is, the features that are specific to the natural language are ignored when comparison decisions are made. This means the decisions are based on simple byte comparisons and ignore casing or equivalence tables that are parameterized by culture." -- Saravanan
