我有一个带有网络表单的网页。我基本上是一个输入字段和一个选择器，但有几个隐藏的字段。我需要向此页面发送POST请求（这基本上是一个搜索页面）。我已按以下方式构建了请求：
HttpClient httpClient = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000);
HttpConnectionParams.setSoTimeout(httpClient.getParams(), 10000);
HttpPost httpPost = new HttpPost("http://www3.u-szeged.hu/kereses_terem.ivy");
httpPost.setHeader("Content-Type", "multipart/form-data");
httpPost.setHeader("name", "search-terem");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("qsearch", "601"));
nameValuePairs.add(new BasicNameValuePair("medium-subtype", "meta-KOD"));
//and a lot of other parameters, please read on
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpClient.execute(httpPost);
我已经使用Fiddler2捕获了已发送的请求，这是原始请求：
POST **************** HTTP/1.1

name: search-terem

如果在浏览器中发送表单，则这是发送的请求：

//and so on
这显然不一样，因此服务器响应0结果。我该如何发送这样的POST请求？谢谢！
