在delphi中模拟IE的清除cookies操作

需要引用ShellApi, ShlObj, WinInet三个单元文件

Delphi利用下面的函数即可实现清除IE的缓存：

function GetCookiesFolder:string;
var
pidl:pItemIDList;
buffer:array [ 0..255 ] of char ;
begin
SHGetSpecialFolderLocation(
application.Handle , CSIDL_COOKIES, pidl);
SHGetPathFromIDList(pidl, buffer);
result:=strpas(buffer);
end;
function ShellDeleteFile(sFileName: string): Boolean;
var
FOS: TSHFileOpStruct;
begin
FillChar(FOS, SizeOf(FOS), 0); {记录清零}
with FOS do
begin
wFunc := FO_DELETE;//删除
pFrom := PChar(sFileName);
fFlags := FOF_NOCONFIRMATION;
end;
Result := (SHFileOperation(FOS) = 0);
end;

//删除cookies
procedure DelCookie;
var
dir:string;
begin
try
InternetSetOption(nil, INTERNET_OPTION_END_BROWSER_SESSION, nil, 0);
dir:=GetCookiesFolder;
ShellDeleteFile(dir+'\*.txt'+#0);
except
abort;
end;

end;
