RefreshConstants enumeration
Contains values used with the IWebBrowser2::Refresh2 method.
Constants
REFRESH_NORMAL
Refresh without sending a "Pragma:no-cache" HTTP header to the server.REFRESH_IFEXPIRED
Refresh if the page has expired.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 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.
