Question

So I am working on a project which uses ASP.NET. I am trying to call Cache[‘key’] but the compiler complains about how System.Web.Caching.Cache is ‘nat valid at this point’.

If I call Cache obj = new Cache(); the obj is always null.

I can access HttpContext.Current.Cache – but this doesnt let me specify an absolute expiration and sliding expiration in the Insert() method.

Can someone help me?

You should be able to absolute or sliding expiration calling the insert on HttpRuntime.Cache. It has several overloads. Ex:

HttpRuntime.Cache.Insert('EXAMPLE_KEY',                          exampleItem,                          Nothing,                                                    DateTime.Now.AddHours(1),                         System.Web.Caching.Cache.NoSlidingExpiration); 

The exact same code should also work with HttpContext.Current.Cache.
