RefreshConstants Enumeration

  • Article

Contains values used with the Refresh2 method.

Syntax

Enum RefreshConstants
    REFRESH_NORMAL = 0
    REFRESH_IFEXPIRED = 1
    REFRESH_COMPLETELY = 3
End Enum

Constants

  • REFRESH_NORMAL
    Refresh without sending a "Pragma:no-cache" HTTP header to the server.
  • REFRESH_IFEXPIRED
    Not currently supported.
  • REFRESH_COMPLETELY
    Refresh without forced cache validation by sending a "Pragma:no-cache" header to the server (HTTP URLs only). Same as pressing Ctrl+F5 in Windows Internet Explorer.

Remarks

The "Pragma:no-cache" header tells the server not to return a cached copy but to ensure that the information is as fresh as possible. Browsers typically send this header when the user selects Refresh , but the header can cause problems for some servers.
