Namespace: System.Web
Assembly: System.Web (in system.web.dll)

public void Execute (
	string path,
	TextWriter writer
public void Execute (
	String path, 
	TextWriter writer
public function Execute (
	path : String, 
	writer : TextWriter
Not applicable.



The URL path to execute.


The TextWriter to capture the output.

Exception typeCondition


The current HttpContext is a null reference (Nothing in Visual Basic).

- or -

An error occurred while executing the handler specified by path.


path is a null reference (Nothing in Visual Basic).

- or -

path is not a virtual path.

The Execute method continues execution of the original request after execution of the virtual path specified is completed. The Transfer method unconditionally transfers execution to another handler.

ASP.NET does not verify that the current user is authorized to view the resource delivered by the Execute method. Although the ASP.NET authorization and authentication logic runs before the original resource handler is called, ASP.NET directly calls the handler indicated by the Execute method and does not rerun authentication and authorization logic for the new resource. If your application's security policy requires clients to have appropriate authorization to access the resource, the application should force reauthorization or provide a custom access-control mechanism.

You can force reauthorization by using the Redirect method instead of the Execute method. Redirect performs a client-side redirect in which the browser requests the new resource. Because this redirect is a new request entering the system, it is subjected to all the authentication and authorization logic of both Internet Information Services (IIS) and ASP.NET security policy.

You can verify that the user has permission to view the resource by incorporating a custom authorization method that uses the IsInRole method before the application calls the Execute method.

The following example executes the Login.aspx page on the server in the current directory and receives the output from the page through the StringWriter object writer. It writes the HTML stream received from writer to the HTTP output stream.

StringWriter writer = new StringWriter();
Server.Execute("Login.aspx", writer);
Response.Write("<H3>Please Login:</H3><br>"+ writer.ToString());

StringWriter writer = new StringWriter();
get_Server().Execute("Login.aspx", writer);
get_Response().Write(("<H3>Please Login:</H3><br>"
    + writer.ToString()));

var writer : StringWriter = new StringWriter()
Server.Execute("Login.aspx", writer)
Response.Write("<H3>Please Login:</H3><br>" + writer.ToString())
