<para>The <see cref="T:System.Web.Caching.AggregateCacheDependency" /> class monitors a collection of dependency objects so that when any of them change, the cached item is automatically removed. The objects in the array can be <see cref="T:System.Web.Caching.CacheDependency" /> objects, <see cref="T:System.Web.Caching.SqlCacheDependency" /> objects, custom objects derived from <see cref="T:System.Web.Caching.CacheDependency" />, or any combination of these. </para>
<para>The <see cref="T:System.Web.Caching.AggregateCacheDependency" /> class differs from the <see cref="T:System.Web.Caching.CacheDependency" /> class in that it allows you to associate multiple dependencies of different types with a single cached item. For example, if you create a page that imports data from a SQL Server database table and an XML file, you can create a <see cref="T:System.Web.Caching.SqlCacheDependency" /> object to represent a dependency on the database table and a <see cref="T:System.Web.Caching.CacheDependency" /> to represent the dependency on the XML file. Rather than making an <see cref="M:System.Web.Caching.Cache.Insert(System.String,System.Object)" /> method call for each dependency, you can create an instance of the <see cref="T:System.Web.Caching.AggregateCacheDependency" /> class with each dependency added to it. You can then use a single <see cref="Overload:System.Web.Caching.Cache.Insert" /> call to make the page dependent on the <see cref="T:System.Web.Caching.AggregateCacheDependency" /> instance.</para>

<para>This method assigns a unique identifier to each dependency in the array and returns each of them. The identifier is a combination of either the file name (for a file dependency) or the key name (for a cache-key dependency) and a string that this method assigns to the dependency.</para>
