This class specifies the attributes that can be set on user controls for fragment caching. To enable fragment caching, use the <OutputCache> directive at the beginning of the appropriate .ascx file. ASP.NET will automatically generate this attribute when the user control is requested. Alternatively, you can leave out the directive and use this attribute in the code-behind class for the user control.
