For a complete example, see the HttpResponse class.

Visual Basic

' Set the page's content type to JPEG files
' and clear all response headers.
Response.ContentType = "image/jpeg"
Response.Clear()

' Buffer response so that page is sent
' after processing is complete.
Response.BufferOutput = True

// Set the page's content type to JPEG files
// and clear all response headers.
Response.ContentType = "image/jpeg";
Response.Clear();

// Buffer response so that page is sent
// after processing is complete.
