Headers from Remote Server with CDN

I have a CDN that is storing me开发者_StackOverflow中文版dia files. Each file I want to store as just the ID number of the file in the data so, file.zip = 4423342 on the server. The problem is, the CDN does not allow php or any form of programming. How can I make it so I have a local file that is used to set the headers and let me change it so when they download a file from the CDN it downloads as file.zip instead of 4423342. Now I know this is simple if the file is stored on the same server as the file that sets the headers.

Thanks!

If your CDN doesn't allow you to set the name/headers of the stored file, you cannot do it on your server. The user gets directed to the CDN server, and you can't "inject" anything into that connection.

I would look into looking up the options your CDN does offer. For example, you might be able to append something like /file.zip to the end of the CDN url, and still get the correct file.

That is – if the CDN url is http://cdn.example.com/113312, maybe http://cdn.example.com/113312/file.zip works as well.
