Never Expiried Application Cache

Look here at section 'To add an item to the Cache with expiration policies':
Adding Items to the Cache[^]

There are expiration policies.
The Cache class defines two fields that do this automatically: NoAbsoluteExpiration and NoSlidingExpiration. Simply set the appropriate parameter to its corresponding field value when you define an absolute or sliding expiration.

cache expirations[^]

If it's an asp.net application, nothing will prevent the cache from deleting when the application shuts down because of no activity.

Hi All,

This source what i have used to create cache object.Also i have checked if "AppCache_Caption" cache object is available or not.

if (HttpRuntime.Cache["AppCache_Caption"] == null){HttpRuntime.Cache.Insert("AppCache_Caption", dicCache, null,System.Web.Caching.Cache.NoAbsoluteExpiration,System.Web.Caching.Cache.NoSlidingExpiration,System.Web.Caching.CacheItemPriority.Normal,null);}

Right now i have checked and created my login page page_load event. It will create cache object every time me access the login page.

What are the conditions wrong my source?

My expectation, cache object creates only one time.It will not create everytime.

Please help me

Thanks in advance
