How can i allow downloads only from my site?

How can i allow downloads only from my site?

Hey,

Say i got 2 domains. one is www.test.com the other is www.site.com

My main site is www.site.com and my downloads are hosted on www.test.com

Lets say for example the file is www.test.com/file.rar

And i want people to download it ONLY when they are on my main site which is www.site.com

So when they are on the main site, the download will work, and when they are not it will not work.

How can i do this?

Thanks.

 

What you're talking about is external linking or "hot linking"
I did a quick search and found this:

sounds like they want the opposite of that of only allowing hotlinking

I am sure you could do it with .htaccess if you are on an apache server alternatively it would be hard to code it in any serverside langauge

 

Well i dont want people to download off my links they got from somewhere else, i want the download links to work only when they are on my main site...

How can i do that?

 

i wonder if that's possible since the two site's are on two different domain names, if they were two different sub domain i think there is a possibility.

 

You can Do it with .htacces
I'm not sure but Try this :
create .htaccess at test.com

 

You would need to do a deny from the all other sources - we dont use Apache servers so dont know .htaccess at all.

The other simple way of doing it is to have the true file out of the public domain and link to a aspx/ php file which checks the referrer is from the correct domain, if it is then to serve up the file and if it isnt then to display an error message/ redirect etc

 

Thanks for the replies.

Can you show me how i would do that? Any toturial? Because thats exactly what i need

Thanks again

 

the code below is a basic example in ASP/ VB.Net to achieve what you want - if you have multiple files you would remove the hard coding of the filename but instead request a querystring element that contains the file name so that the one downloader could be used for all the files.

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Request.UrlReferrer.Host.Contains("test.com") Then
            Dim path As String = Server.MapPath("thefilename.zip")
            Dim file As System.IO.FileInfo = New System.IO.FileInfo(path)
            If file.Exists Then 'set appropriate headers
                Response.Clear()
                Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)
                Response.AddHeader("Content-Length", file.Length.ToString())
                Response.ContentType = "application/octet-stream"
                Response.WriteFile(file.FullName)
                Response.End()
            Else
                '''' enter action for if the file doesnt exist
            End If
            file = Nothing
        Else
            '''' if from invalid link redirect
            Response.Redirect("http://www.test.com")
        End If
    End Sub
