下載文件從短網址

我想從一個簡短的網址下載一個聲音文件（如：www.adjix.com）當我從正常的鏈路嘗試，這是好的，但是從短網址，如何第一重定向，然後下載下載文件從短網址

我使用這部分代碼來創建一個請求：

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlToSound]]; 

NSURLConnection *theConnection =[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 

if (theConnection) { 
    self.receiveData = [[NSMutableData data] retain]; 
}

而這種代碼來查看頭：

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ 
    [receiveData setLength:0]; 

    if ([response isKindOfClass:[NSHTTPURLResponse self]] ) { 
     NSDictionary *headers = [(NSHTTPURLResponse *)response allHeaderFields]; 
     NSLog(@"headers: %@", headers); 
    } 
}

當我嘗試直接下載，鏈接到MP3頭呃是：

"Accept-Ranges" = bytes; 
    Connection = "Keep-Alive"; 
    "Content-Length" = 21316; 
    "Content-Type" = "audio/mpeg"; 
    Date = "Sat, 07 Feb 2009 16:01:34 GMT"; 
    Etag = "\"2d810-5344-7dda240\""; 
    "Keep-Alive" = "timeout=15, max=100"; 
    "Last-Modified" = "Sat, 25 Jun 2005 12:26:41 GMT"; 
    Server = Apache;

當我嘗試下載文件用短URL（adjix.com/3na3），標題是：

"Cache-Control" = "max-age=60"; 
    Connection = close; 
    "Content-Length" = 692; 
    "Content-Type" = "text/html"; 
    Date = "Sat, 07 Feb 2009 19:18:23 GMT"; 
    Expires = "Sat, 07 Feb 2009 19:19:23 GMT"; 
    Server = "Apache/1.3.41 (Darwin) mod_ssl/2.8.31 OpenSSL/0.9.7l";
