RefreshConstants Enumeration

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.

Enumeration Information

Minimum availability Internet Explorer 4.0
Minimum operating systems Windows NT 4.0, Windows 95, Windows CE 2.12
