Application and Cache both help to share global data and cache data
across the users.but cache object is proactive and you can define dependency.In
application object you can't define depenency.
Below is the code for declaring application and cache object.
CacheDependency objCacheDependency = new CacheDependency(Server.MapPath
Cache.Insert("Banner", strBanner, objCacheDependency);
Application["Banner"] = "strBanner";
In the above code, for Cache object you can define dependency but in
Application object you can't define dependency.when the banner file is changed
the Cache object can be refreshed but the application remain static and holds
the old text of banner file.
