我用idhttp登录一个https的网站，主要代码如下：
IdHTTP1.AllowCookies := False;
IdHTTP1.ReadTimeout := 20000;
IdHTTP1.Request.Host := 'upay.10010.com';
//设置cookie,我是先用webbrower获取的登录页cookie，验证码也取到了，
IdHTTP1.Request.CustomHeaders.Text :='Cookie: '+WebBrowser1.OleObject.document.cookie;
IdHTTP1.Request.Referer := 'https://upay.10010.com/web/BankCharge/BankChargeInit'; //请求来路
IdHTTP1.Request.AcceptEncoding := 'gzip, deflate';
IdHTTP1.Request.AcceptLanguage := 'zh-cn,utf-8;q=0.5';
IdHTTP1.Request.Accept := 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,'
