Apache HttpClient 4.0. Weird behavior

I'm using Apache HttpClient 4.0 for my web crawler. The behavior i found strange is: i'm trying to get page via HTTP GET method and getting response about 404 HTTP error. But if i try to get that page using browser it's done successfully.

Details: 1. I upload multipart form to server this way:

    HttpPost httpPost = new HttpPost("http://[host here]/in.php");

    MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    entity.addPart("method", new StringBody("post"));
    entity.addPart("key", new StringBody("223fwe0923fjf23"));
    FileBody fileBody 开发者_如何学Python= new FileBody(new File("photo.jpg"), "image/jpeg");
    entity.addPart("file", fileBody);
    httpPost.setEntity(entity);

    HttpResponse response = httpClient.execute(httpPost);       
    HttpEntity result = response.getEntity();

    String responseString = "";
    if (result != null) {
        InputStream inputStream = result.getContent();

        byte[] buffer = new byte[1024];
        while(inputStream.read(buffer) > 0)
            responseString += new String(buffer);

        result.consumeContent();
    }

Uppload succefully ends.

2. I'm getting some results from web server:

       HttpGet httpGet = new HttpGet("http://[host here]/res.php?key="+myKey+"&action=get&id="+id);
   
       HttpResponse response = httpClient.execute(httpGet);
       HttpEntity entity = response.getEntity();
   

I'm getting ClientProtocolException while execute method run. I was debugging this situation with log4j. Server answers "404 Not Found". But my browser loads me that page with no problem.

Can anybody help me?

Thank you.

I have to note the problem isn't concerned with web server. If i don't add FileBody to multipart form data, exception doesn't occure, all goes fine with no HTTP 404.
