MemoryCache Aspnet MVC

Question

i've a problem for implement a MemoryCache object in aspnet. This is my code

        ObjectCache cache = MemoryCache.Default;
        CacheItemPolicy policy = new CacheItemPolicy();
        policy.AbsoluteExpiration = DateTimeOffset.Now.AddSeconds(10.0);
        cache.Add("keyName", resultQuery, policy);

The object is correct insert in the cache but when i delete and rewrite it the new object in the view is visible only in my session.

        var q = queryObject;
        var cacheKey = "keyName";
        MemoryCache.Default.Remove(cacheKey);
        ObjectCache cache = MemoryCache.Default;
        CacheItemPolicy policy = new CacheItemPolicy();
        policy.AbsoluteExpiration = DateTimeOffset.Now.AddSeconds(10.0);
        cache.Add(cacheKey, q, policy);

And this is the simple Get Implementation.

        cache.Get(cacheKey);

I don't understand why sometimes works in different browser session and sometimes doesn't work. Someone can help me? Thanks.

Use the System.Web.Caching.cache Use this code to get Cache

public string[] GetCache() {

string[] cache = Cache["names"] as string[];
if(names == null)
{
cache= DB.GetCache();
Cache["names"] = cache;
}
return cache;

}
