    <summary>Defines the metadata attribute that Web Forms user controls (.ascx files) use to indicate if and how their output is cached. This class cannot be inherited.</summary>

## Remarks  
  
> [!IMPORTANT]
> Output caching is a performance optimization feature. The `VaryBy` settings are designed to cache alternate representations of a resource based on request characteristics; they are not designed to isolate audiences or classes of content. Do not rely on cache variation to separate personalized, tenant-specific, authorization-dependent, or otherwise sensitive responses. Enforce any required isolation between request contexts independently of the cache configuration.
  
 The <xref:System.Web.UI.PartialCachingAttribute> attribute class marks user controls (.ascx files) that support fragment caching, and encapsulates the cache settings that ASP.NET uses when caching the control. Page and controls developers use the <xref:System.Web.UI.PartialCachingAttribute> attribute to enable output caching for a user control in a code-behind file.  
  
 Using the <xref:System.Web.UI.PartialCachingAttribute> is one of several ways you can enable output caching. The following list describes methods you can use to enable output caching.  
  
-   Use the `@ OutputCache` directive to enable output caching in declarative scenarios.  
  
-   Use the <xref:System.Web.UI.PartialCachingAttribute> to enable caching for a user control in a code-behind file.  
  
-   Use the <xref:System.Web.UI.ControlCachePolicy> class to programmatically specify cache settings in programmatic scenarios in which you are working with <xref:System.Web.UI.BasePartialCachingControl> instances.  
  
 If a user control contains an `@ OutputCache` directive or has a <xref:System.Web.UI.PartialCachingAttribute> applied, the ASP.NET parser generates an instance of the <xref:System.Web.UI.PartialCachingControl> class to wrap the user control.  
  
 For more information about ASP.NET caching, see [Caching](https://learn.microsoft.com/previous-versions/aspnet/xsbfdd8c(v=vs.100)). For more information about using attributes, see [Attributes](/dotnet/standard/attributes/).  
  
   
  
## Examples  
 The following code example demonstrates using the <xref:System.Web.UI.PartialCachingAttribute>. This example has three parts:  
  
-   A partial class, `ctlMine`, that inherits from the <xref:System.Web.UI.UserControl> base class and to which the <xref:System.Web.UI.PartialCachingAttribute> attribute is applied.  
  
-   A user control that is used with the `ctlMine` partial class.  
  
-   A Web Forms page that hosts the user control.  
  
 The first part of the example demonstrates a partial class that inherits from the <xref:System.Web.UI.UserControl> base class and to which the <xref:System.Web.UI.PartialCachingAttribute> attribute is applied. In this example, the attribute specifies that the user control should be cached for 20 seconds.

 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_WebNet/PartialCachingAttribute_1/VB/partialcache.vb.ascx.vb" id="Snippet1":::  
  
 The second part of the example shows a user control that is used with the previous example to demonstrate user control caching.

## Examples  
 The following code example demonstrates how the <xref:System.Web.UI.PartialCachingAttribute.%23ctor%28System.Int32%29> constructor can be applied to a user control. In the example, the constructor is used to indicate that the user control can be cached and to specify the caching duration. This code example is part of a larger example provided for the <xref:System.Web.UI.PartialCachingAttribute> class.

## Examples  
 The following code example demonstrates how the <xref:System.Web.UI.PartialCachingAttribute.%23ctor%28System.Int32%29> constructor can be applied to a user control. The attribute indicates that the user control can be cached and specifies a 20 second caching duration. This code example is part of a larger example provided for the <xref:System.Web.UI.PartialCachingAttribute> class.

## Remarks  
 If you set this property to `true`, cached user control output can be accessed by multiple Web Forms pages. If you do not set it to `true`, the default behavior is to cache one version of user control output for each page that contains that user control. You can potentially save a significant amount of memory by enabling this property.

If you use SQL Server 2005, you can set the <xref:System.Web.UI.PartialCachingAttribute.SqlDependency%2A> property to "CommandNotification", which instructs ASP.NET to create row level dependencies for all SQL commands issued within the context of the current ASP.NET page.

## Remarks  
 If you specify "browser" for this property, the user control will be varied by browser type and major version number. You can also use this property to extend the values that output cache varies the user control response.  
  
   
  
## Examples  
 The following code example demonstrates how the <xref:System.Web.UI.PartialCachingAttribute.%23ctor%28System.Int32%2CSystem.String%2CSystem.String%2CSystem.String%29> constructor can be applied to a user control. In the example, the constructor is used to indicate that the user control can be cached and to specify that the cache entry is dependent on the browser type and major version number.
