The begin.
Response:=TStringStream. Create (");
PostList:=TStringList. Create;
Try
IdHTTP1. Request. UserAgent:='Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Maxthon) ';

I write so that it can be:
IdHTTP1. Post (' http://www.zhezhisd.cn/admin_in.asp/? id=admin& Ps=1 ', postList, Response);
And like the above submission is not successful, could you tell me why? The post of the second parameter is not used to submit some parameters?
