Timeout for an existing cache object .Net

Question

I am building an MVC web application, and I have a few objects in the cache inserted by the following statement:

HttpContext.Current.Cache.Insert("CacheKey", "CachedValue");

I know that I can add a timeout by using the following when inserting an item to the cache:

HttpContext.Current.Cache.Insert("CacheKey", "CachedValue", null, DateTime.Now.AddMilliseconds(10000), Cache.NoSlidingExpiration);

However, my specific requirements are updating the cache timeout once the items have been inserted in the cache. So basically, I need to add a timeout to an existing item in the cache. How would I go about in doing that?

Any help would be appreciated.

could you give me the code to do that? I can fetch the item by HttpContext.Current.Cache["CacheKey"] but how do I add a timeout to this object? — TK1

does it update the item in the cache if I do an insert again for the same key? — TK1

Bit late to the show, but you could do the following, drop the cache and then re-cache with new data. i.e HttpContext.Current.Cache.Remove(your cache id);

Hope it helps

Ok, I found the answer to my question. If I use the insert method, it updates an existing value if there is an object in the cache with the same key.
