用IE测试,HttpWatch监控,输入帐号并登录,login.php返回302重定向,可以监视到IE获取到其中一个PHPSESSID的cookie.
如下:



 00:00:00.000		0.183	497	772	GET	200	text/html	http://www.a1a999.com/

 00:00:00.223		0.186	610	2438	GET	200	text/html	http://www.a1a999.com/home.php

 00:00:01.171		0.200	410	2315	GET	200	image/jpeg	http://www.a1a999.com/images/button_bg.jpg

 00:00:24.200		0.205	766	623	POST	302	Redirect to http://www.a1a999.com/check_rule.php?PHPSESSID=&password_modify_date=2011-01-31%2011:20:52	http://www.a1a999.com/login.php

 00:00:24.407		0.383	741	3057	GET	200	text/html; charset=gb2312	http://www.a1a999.com/check_rule.php?PHPSESSID=&password_modify_date=2011-01-31%2011:20:52

 00:00:24.842		1.643	508	35969	GET	200	image/jpeg	http://www.a1a999.com/images/banner.wg.jpg

 00:00:24.845		0.390	512	2317	GET	200	image/jpeg	http://www.a1a999.com/images/button_bg_red.jpg

 00:00:24.872		0.364	514	2316	GET	200	image/jpeg	http://www.a1a999.com/images/button_bg_green.jpg

//////////

在 00:00:00.000这一步,IE首先获取到一个Cookie.

NSC_63.217.93.116	Received	ffffffff091a183545525d5f4f58455e445a4a423660	/	www.a1a999.com	(Session)



然后在 00:00:24.200这一步,即输入帐号密码登录后,login返回302重定向后IE再次获取PHPSESSID这个Cookie

NSC_63.217.93.116	Sent	ffffffff091a183545525d5f4f58455e445a4a423660	/	www.a1a999.com	(Session)

NSC_63.217.93.116	Received	ffffffff091a183545525d5f4f58455e445a4a423660	/	www.a1a999.com	(Session)

PHPSESSID Received	0vib8n0n4vi9i0m6t0201q45e5	/	www.a1a999.com	(Session)

问题是:
如果用idhttp去登录,却获取不到这个PHPSESSID的cookie.
测试如下:



			RequestData->Clear();

			try

			{

				IdHTTP1->Get(WebAddress,RequestData);

			}

			catch(...)

			{

				MemoInfo->Lines->Add("连接错误");

				return;

			}

			RequestData->SaveToFile("login0.txt");

			MemoInfo->Lines->Add("请求头:"+IdHTTP1->Request->RawHeaders->Text);

			MemoInfo->Lines->Add("响应头:"+IdHTTP1->Response->RawHeaders->Text);

            MemoInfo->Lines->Add("Location:"+IdHTTP1->Response->Location);

			RequestData->Clear();

			try

			{

				IdHTTP1->Get(WebAddress+"/home.php",RequestData);

			}

			catch(...)

			{

				MemoInfo->Lines->Add("连接错误");

				return;

			}

			RequestData->SaveToFile("login1.txt");

			MemoInfo->Lines->Add("请求头:"+IdHTTP1->Request->RawHeaders->Text);

			MemoInfo->Lines->Add("响应头:"+IdHTTP1->Response->RawHeaders->Text);

			MemoInfo->Lines->Add("Location:"+IdHTTP1->Response->Location);

			char *ss=strstr(RequestData->DataString.c_str(),"login.php");

			if (!ss) {

				MemoInfo->Lines->Add("连接错误2");

				return;

			}



			PostParam->Clear();

			PostParam->Add("login=登入");

			PostParam->Add("username="+UserName);

			PostParam->Add("password="+Password);

			RequestData->Clear();

			try

			{

				IdHTTP1->Post(WebAddress+"/login.php",PostParam,RequestData);

			}

			catch(...)

			{

				MemoInfo->Lines->Add("连接错误3");

				return;

			}

			RequestData->SaveToFile("login2.txt");

			MemoInfo->Lines->Add("请求头:"+IdHTTP1->Request->RawHeaders->Text);

			MemoInfo->Lines->Add("响应头:"+IdHTTP1->Response->RawHeaders->Text);

			MemoInfo->Lines->Add("Location:"+IdHTTP1->Response->Location);

监控结果如下:

即idhttp既无重定向响应,也无法获取到PHPSESSID的cookie.idhttp设置已正常,AllowCookie=true,允许重定向.

求解..
