Mp3 file download as .aspx file and not open on phone player

I have the same problem , i also create a mobile application ain asp.net to download mp3 file on cell phone.
But i find that when i access the page from cell phone , file save and displayed as wapauthenticate.aspx not as <filename>.mp3, opened by the media player after downloading?

For more reference i add my download code

asp Code:

Original - asp Code

string Name = dsDownload.Tables[0].Rows[0]["RingtoneFileName"].ToString();
string Format = dsDownload.Tables[0].Rows[0]["RingtoneFileFormat"].ToString();
string strFileName = Name + "." + Format;
 
//THIS CODE IS WRITTEN TO INCREMENT THE NO OF COUNT IN THE DATABASE
//IncrementFileDownloadCount(RingtoneID);
//CODE END
string originalFilename = strFileName;
string localfilename = Server.MapPath("~/RingtoneFiles") + "/" + strFileName;
WebClient req = new WebClient();
CredentialCache mycache = new CredentialCache();
mycache.Add(new Uri(localfilename), "Basic", new NetworkCredential("administrator", "admin$123"));
req.Credentials = mycache;
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ClearContent();
response.ClearHeaders();
response.Buffer = true;
response.AddHeader("Content-Disposition", "attachment;filename=\"" + originalFilename + "\"");
Response.AddHeader("Content-Type", "audio/mpeg");
byte[] data = req.DownloadData(localfilename);
response.BinaryWrite(data);
response.End();
return;

Please help me out from this problem

Hi yoge, I know next to nothing about .net programming,
but I feel that you need to add filesize(Content-length) at least as a "response.AddHeader".

HTH.

try>> http://website/download.aspx/myringtone.mp3

if you have download link : http://website/download.aspx?id=1234, most mobile will save the content you're flushing using "download.aspx" as file name instead of what you have specified in Content-Disposition header

as you can see, most mobile will use the file name its accessing into, so...to solve this problem you can put the url instead into this one :
http://website/download.aspx/myringtone.mp3
to ensure the phone to save it as "myringtone.mp3"

the question is, "hey, it will return HTTP 404 Error File Not Found", but fortunately asp.net and php already that smart that they know we're actually want to access "download.asp" instead of "myringtone.mp3"
so...when ever user contact url http://website/download.aspx/myringtone.mp3, they will contact "download.aspx", instead of giving error
try it...

***

now...its my turn, I'm still using the "old" asp, and unfortunately the feature I said above is not yet available
I just cant simply use url : http://website/download.aspx/myringtone.mp3, it will give either HTTP 404 not found or...HTTP 500 IIS Error

so, if anyone who know how-to solve this problem in asp, pls advice, thx...
