Syntax

BOOL InternetSetCookie%(
    IN LPCTSTR% lpszUrl,
    IN LPCTSTR% lpszCookieName,
    IN LPCTSTR% lpszCookieData
);

The actual syntax of this function varies between its ANSI and Unicode implementations. See the Win32 Internet Functions Syntax document for details.

Parameters

lpszUrl

Address of a null-terminated string that specifies the URL for which the cookie should be set.

lpszCookieName

Address of a string that contains the name to associate with the cookie data. If this parameter is NULL, no name is associated with the cookie.

lpszCookieData

Address of the actual data to associate with the URL.

Return Value

Returns TRUE if successful, or FALSE otherwise. To get a specific error message, call GetLastError.

Remarks

Cookies created by InternetSetCookie without an expiration date are stored in memory and are available only in the same process that created them. Cookies that include an expiration date are stored in the windows\cookies directory.

Creating a new cookie might cause a dialog box to appear on the screen if the appropriate registry value, AllowCookies, is set. There is no way to change the registry value from a Win32® Internet function.
