hi,
I am using httpruntime to cache certain objects in my application. I
need to store 4 objects in cache. but the cache items are being
removed from cache after 20-30 seconds. it is working fine if i store
only 3 objects. i am using .net 1.1. The reason i am getting in the
callback method is 'removed'.

Does anyone know how to fix this?

Thanks,
Sammy

The cache object makes no explicit guarantee that your items will be
available when you are ready to use it. Your logic should first test to see
if the object is available, it isn't then call a method to replenish the
cache. You may also want to bump the priority of the items in the cache so
that they are more immune to cache purges. Again, there's absolutely no
guarantee that this technique will result in items being always present in
the cache.

HI all,

Add the object this way.

Cache.Insert("KeyCahe", yourObject, null, DateTime.Now.AddMinutes(20),
TimeSpan.Zero);

AddMinutes(20), set the cache to expires in 20 minutes.
