REFRESHCONSTANTS Enumerated Type

---

Contains values used with the Refresh2 and IWebBrowser2::Refresh2 methods.

Syntax

typedef enum RefreshConstants {
    REFRESH_NORMAL = 0,
    REFRESH_IFEXPIRED = 1,
    REFRESH_CONTINUE = 2,
    REFRESH_COMPLETELY = 3
} RefreshConstants;

Constants

REFRESH_NORMAL	Refresh that does not include sending the HTTP "pragma:nocache" header to the server.
REFRESH_IFEXPIRED	Refresh that occurs if the page has expired.
REFRESH_CONTINUE	For internal use only; do not use.
REFRESH_COMPLETELY	Refresh that includes sending a "pragma:nocache" header to the server (HTTP URLs only).

Remarks

The "pragma:nocache" 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.
