.NET Framework Class Library
IHttpHandler..::.IsReusable Property

Gets a value indicating whether another request can use the IHttpHandler instance.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)
Syntax

Visual Basic (Declaration)
ReadOnly Property IsReusable As Boolean
Visual Basic (Usage)
Dim instance As IHttpHandler
Dim value As Boolean

value = instance.IsReusable
C#
bool IsReusable { get; }
Visual C++
property bool IsReusable {
    bool get ();
}
JScript
function get IsReusable () : boolean

Property Value

Type: System..::.Boolean
true if the IHttpHandler instance is reusable; otherwise, false.
Remarks

You explicitly set the IsReusable property to true or false by code you provide that overrides the IsReusable property accessor (getter).

Examples

The following code example writes four lines of text to the HTTP output stream in response to a client request for a page named handler.aspx. All requests for handler.aspx are serviced by the MyHttpHandler class in the namespace HandlerExample contained in the assembly HandlerTest.dll.

Visual Basic
' Name this Visual Basic file HandlerTest.vb and compile it with the
' command line: vbc /target:library /r:System.Web.dll HandlerTest.vb.
' Copy HandlerTest.dll to your \bin directory.
Imports System.Web
