关于用IDhttp发送网站http头的问题

近来发现在一个怪问题，第一次发送http头反回数据都正常，但第二次就不正常了，因为第一次请求时返回了一个cookie 。第二次发送时就连这个cookie 也发过去了。本来也没错，但就是这个cookie 的位置不对，倒置发送的http头错误。

看下面的的第一次请求正常:
GET http://www.paymesurf.com:80/surf3.php?usrid=879 HTTP/1.1
Content-Type: text/html
Proxy-Connection: Keep-Alive
Host: www.paymesurf.com
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-powerpoint, application/vnd.ms-excel, application/msword, application/x-shockwave-flash, */*
Accept-Language: zh-cn
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; MyIE2; CustomExchangeBrowser; .NET CLR 1.1.4322)
 
返回数据:
HTTP/1.0 200 OK

Server: Apache/1.3.33 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.10 FrontPage/5.0.2.2635 mod_ssl/2.8.22 OpenSSL/0.9.7a

第二次请求就变成这样了：
GET http://www.paymesurf.com:80/bar3.php?usrid=879&PHPSESSID=66b3ae6788a076324ad5c62e8fcaedbe HTTP/1.1
Content-Type: text/html
PHPSESSID=66b3ae6788a076324ad5c62e8fcaedbe    //在这里就多了这一句，所以出错了。
Proxy-Connection: Keep-Alive

令人奇怪的是，在我的电脑里运行正常，而发给别人用就不正常，是不是因为我的电脑里有indy的组件呢。还是什么原因，郁闷呀,哪位大哥可以帮我解答呀。QQ:402391462 ，注明：idhttp。谢谢

代码如下：

第一次请求：
     idsearch.Request.Accept:='image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-powerpoint, application/vnd.ms-excel, application/msword, application/x-shockwave-flash, */*';
    idsearch.Request.AcceptLanguage:='zh-cn';
    idsearch.Request.UserAgent:='Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; MyIE2; CustomExchangeBrowser; .NET CLR 1.1.4322)';
    idsearch.Request.ProxyConnection:='Keep-Alive' ;
    idsearch.Request.ContentType:='text/html';
    SurfUrl:='http://www.paymesurf.com:80/surf3.php?usrid=879 '
    tmpstr:=idsearch.Get(SurfUrl);
    if  tmpstr='' then
        writeLog('连接网站失败..')
    else
        writeLog('连接网站成功..');
:第二次请求:
cookiestr:='cookie :asdfjiwerfksldafjiweflkasdjfiw'
idsearch.Request.CustomHeaders.Text:=cookiestr;
surfurl1:='http://www.paymesurf.com:80/bar3.php?usrid=879 '
    idsearch.request.Referer:=SurfUrl;
 try
        tmpstr:=idsearch.get(surfurl1);
    except
          writeLog('失败..');
    end;
就是这里返回数据出错了。

如何解决呀。
