How hide a download url from our web site

Question

I have the following code in my page:

if (Request.QueryString("link_id") == "12345" )
{
    Responce.Redirect("http://www.downloadsite.com/blablabla.png");
}

Now I want to hide that URL when somebody adds this link to his internet download manager :

http://www.mysite.com?link_id=12345

as you see the goal domain in different, I just want prevent my users to share my links.

Thanks in advance.

I'm not entirely clear on what you're trying to do...are you saying that you want it to appear as if they're downloading from `http://www.mysite.com?link_id=12345` instead of `http://www.downloadsite.com/blablabla.png`? — Tim S., Jun 16 '13 at 13:04
tinyurl is not a good idea, because at last my users can find main link... — SilverLight, Jun 16 '13 at 18:21

If I understand the question, you're trying to let the user download a file from http://www.downloadsite.com/blablabla.png that appears to the user, in every sense, to be coming from http://www.mysite.com?link_id=12345. This is what I'd try:

if (Request.Params["link_id"] == "12345")
{
    Uri uri = new Uri("http://www.downloadsite.com/blablabla.png");
    using (var wc = new WebClient())
    using (var download = wc.OpenRead(uri))
    using (var respStream = Response.OutputStream)
        download.CopyTo(respStream);
}

i am so sorry for my dely, would you please consider to my prev comment! – SilverLight Jun 16 '13 at 18:32
You might be looking to set the `content-disposition` to `attachment`, to tell the browser it should download the content, instead of trying to display it inline. http://stackoverflow.com/questions/1012437/uses-of-content-disposition-in-an-http-response-header You might also want to make sure the MIME type (Content-Type) and any other metadata is set correctly. To see metadata from the original URL, see http://stackoverflow.com/questions/4423061/view-http-headers-in-google-chrome or search for "see http headers". – Tim S. Jun 16 '13 at 19:04
i have many .mkv (movies) next blablabla.png / did your solution work for thsoe files? – SilverLight Jun 16 '13 at 19:14
Yep, it should work for any file type; the only thing that'll be different is the source URL and, if you specify it, the Content-Type. – Tim S. Jun 16 '13 at 19:16
would you please complete your answer for a mkv file, i do n't want that file to be downloaded on my server... – SilverLight Jun 16 '13 at 19:18
