HttpWebResponse response = null;
HttpWebRequest request = null;
CookieContainer container = new CookieContainer();
//container contains all the cookies related to my site
 request = (HttpWebRequest)WebRequest.Create("http://www.mysite.com/a/test.html?id=2&cid=5");

                request.CookieContainer = new CookieContainer();
                request.CookieContainer = container;
                request.Method = "GET";
                request.CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.NoCacheNoStore);
                request.KeepAlive = false;
                request.Timeout = 5000;
                request.Proxy = null;
               
                request.ContentType = "application/ms-word";

                request.Credentials = new NetworkCredential("admin", "password");
                using (response = (HttpWebResponse)request.GetResponse())
                {


                    readStream = response.GetResponseStream();
                    contentType = response.ContentType;

                    path = "E:\\Files";
string extension=string.empty;
                   if (contentType == "text/html")
                    {
                        if (request != null)
                            request = null;
                        return false;

                    }
                    else
                    {
                        if (contentType == "application/rtf")
                        {
                            extension = ".rtf";
                        }
                        else
                        {
                            extension = ".doc";
                        }


                        FileStream writeStream = new FileStream(path + extension, FileMode.Create, FileAccess.Write);
                        ReadWriteStream(readStream, writeStream);//creates the file and writes data to file.

                        if (request != null)
                            request = null;
                        return true;
                    }
                }

in the above example .doc files contains data after downloading. but for .rtf files I am getting "Document server is busy please try after some time" message rather than the actual content.

suppose if i copy paste the url in browser .rtf file contains data..
Please help me guys

Sounds like your session is timing out. Also, unless someone else who reads this has had the exact same problem I doubt anyone can help unless you share some code and more details.

may i know the guys who down voted and why ?
you should give proper reason to down vote something . please let me know...don't be think in negative way and don't make people sad.

Saying don't make people sad will get you down-voted around here.

You've probably been down-voted because you have asked a question without providing sufficient information. None of us (that I'm aware of) are telepathic so there is no way we can know what is going on without some code.

Read over and over again, but I don't understand your question. Can we see some code here?

The question is quite fine for me.
If it is opening up in browser, ideally it should work with web browser control in windows application also. Please let me know the below details:
1) What is the size and other details of the document for which you are having issues with download?
2) In your web application is there any config setting related to this?
3) Are there are any specific settings you set for browser control in your win app?

C#

static public byte[] GetBytesFromUrl(string url)
    {
        byte[] b;
        HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(url);
        WebResponse myResp = myReq.GetResponse();

        Stream stream = myResp.GetResponseStream();
        //int i;
        using (BinaryReader br = new BinaryReader(stream))
        {
            //i = (int)(stream.Length);
            b = br.ReadBytes(500000);
            br.Close();
        }
        myResp.Close();
        return b;
    }

    static public void WriteBytesToFile(string fileName, byte[] content)
    {
        FileStream fs = new FileStream(fileName, FileMode.Create);
        BinaryWriter w = new BinaryWriter(fs);
        try
        {
            w.Write(content);
        }
        finally
        {
            fs.Close();
            w.Close();
        }
    }

XML

private void getDocument(string url )
   {
       
       string DestinationPath = Server.MapPath("targetdocumentspath");
       string filename = url.Substring(url.LastIndexOf('/') + 1);
       byte[] bytes = GetBytesFromUrl(url);
       WriteBytesToFile(DestinationPath + "/" + filename, bytes);
