Question

I get cookie from InternetGetCookieEx on DownloadComplete WebBrwoser. When trying to login to hotmail it get’s through but then get’s redirected. Even though Gmail works.
I am trying to figure out a universal solution to transfer Authenication from WebBrowser to IdCookieManager for Web Parsing.

Cookies aswell as redirects are enabled on IdHTPP.

    function GetCookie(host: string): string;
    const
      INTERNET_COOKIE_HTTPONLY = 8192;
    var
      hModule: THandle;
      lp: Pointer;
      InternetGetCookieEx: function(lpszUrl, lpszCookieName, lpszCookieData
        : PAnsiChar; var lpdwSize: DWORD; dwFlags: DWORD; lpReserved: pointer)
        : BOOL; stdCall;
      CookieSize: DWORD;
      CookieData: PAnsiChar;
    begin
      LoadLibrary('wininet.dll');
      hModule := GetModuleHandle('wininet.dll');
      if hModule <> 0 then
      begin
        @InternetGetCookieEx := GetProcAddress(hModule, 'InternetGetCookieExA');
        if @InternetGetCookieEx <> nil then
        begin
          CookieSize := 1024;
          Cookiedata := AllocMem(CookieSize);
          if InternetGetCookieEx(PAnsiChar(AnsiString(host)), nil, Cookiedata, CookieSize, INTERNET_COOKIE_HTTPONLY, nil) then
          result:=cookiedata;
          FreeMem(Cookiedata);
        end;
      end;
    end;

procedure EmbeddedWB1DocumentComplete(ASender: TObject; const pDisp: IDispatch;
  var URL: OleVariant);
var
  document: IHTMLDocument2;
  cookies: TStringList;
  uri: TIdURI;
begin
  document := EmbeddedWB1.Document as IHTMLDocument2;
  cookies := TStringList.Create;
  try 
    cookies.Delimiter:=';';
    //cookies.DelimitedText:=GetCookie(document.url);
    cookies.DelimitedText:=document.cookie;
    uri := TIdURI.Create(document.url);
    try
      IdCookieManager1.AddServerCookies(cookies,uri);
      EmbeddedWB1.LoadFromString(http.Get(document.url));
    finally
      uri.Free;
    end;
  finally
    cookies.Free;
  end;

Answer 1

As I mentioned in your other question, you need to pre-parse the cookies you are extracting from the web browser. It is not enough to simply split the cookie string as-is on ; characters, since that delimiter is used to both delimit individual cookies from each other as well as delimit name=value data from parameter data within a single cookie. If you just split the entire string without taking that into account, your TStringList is not going to end up with correct cookie data, so you end up passing bad data to TIdCookieManager.

You might also consider using the NavigateComplete/2 events, as the DocumentComplete event might be too late when redirects are involved.
