Topic: Mask And Change A Download Link

Subject: Mask And Change A Download Link
Date Posted: 30 April 2004 at 8:19pm

I was wondering if anyone knows of an ASP Script that will mask a download link and change it everytime a new person clicks to download from that link.

For example:

If I have a file : http://www.mysite.com/files/download.zip - http://www.mysite.com/files/download.zip and I don't want the people downloading it to see where it comes from it shows the link like this http://www.mysite.com/4683jeke83l - http://www.mysite.com/4683jeke83l or something like that and each time a new person it would change the coding http://www.mysite.com/8t4389jk - http://www.mysite.com/8t4389jk but the file would still acutally be http://www.mysite.com/files/download.zip - http://www.mysite.com/files/download.zip

Anyone ever seen anything like this? It doesn't matter if it is just a script by itself or if it is a database driven script.

Thanks in advance!

I think ASP Upload has an option where you can download a file using the Physical Path on the server HDD, so there can be never a link to this file i.e. it doesn't exist through http://yourdomain/yourfile.ext.

Well... i think there are more than 10 Thousand ASP *Random Link* generators are available.

Make some bulk directories in your site.. for example /98798lkdjf9498/

and in that folder's default.asp, write response.redirect "http://yoursite.com/download.zip"

I think this is the only possible way to do it ?

Not sure if this would work, but could the zip be streamed from the ASP file using the objADOStream object.

Simular to how the security_images.asp file works in the forum, but pointing it to a zip file instead and setting the content type to what a browser would regonise as a zip file.

May not work, but could be worth a try, if it does work let me know as I would be interested in such a thing.

Secure File Downloading

With AspUpload, you can let your users download files which are not necessarily residing in a virtual directory, but anywhere on the server's hard drive or even a remote machine.
File downloading is implemented with the method Upload.SendBinary, as follows:
Set Upload = Server.CreateObject("Persits.Upload")
Upload.SendBinary "c:\path\file.ext", True, "application/octet-stream", True

perhaps you can make a directory, like /download/ and put a default.asp in it that has a response.redirect in that which points to your file

further more, you may write a script that randomly renames your /download/ folder into something like 4683jeke83l and store the name that it last time used as an ease for renaming the same directory the next time.

Just had a play around with the security images file in Web Wiz Forums to convert it to download a zip file by calling the ASP file and it worked (in Moizlla Firebird anyway)

Here is the code:-

'Set the stream object

Set objADOStream = server.createobject("ADODB.Stream")



'Open the streem oject

objADOStream.Open



'Set the stream object type to binary

objADOStream.Type = 1



'Load in the zip file

objADOStream.LoadFromFile  Server.MapPath("uploads/web_wiz_forums_SQL_Server_v7.8.zip")







'Set the right response content type for zip file

Response.ContentType = "application/x-zip-compressed"



'Send zip to browser

Response.BinaryWrite objADOStream.Read



'Flush the response object

Response.Flush





'Clean up

objADOStream.Close

Set objADOStream=Nothing

OK, a bot premiture, 1 problem I have discovered is that it saves the zip file with the same name and extension as your ASP page. But there maybe away around that.

There is a way around that:

Response.AddHeader "Content-disposition", "filename=thefile.zip"

Thanks Mart that does the trick.

I think I'll start using it for this site, to prevent people from linking directly to the files.

Wow this is great! Exactly the kind of thing I was looking for.

My whole point is like you said -boRg- :

This is exactly what I was thinking, which is why I wanted something like this!
