POC - Secure File Downloads

I'm after some Proof of Concept Code, written using php & mySQL and also potentially asp.net and MS-SQL (please speciy if you have both php/mysql and [url removed, login to view] or just php/mysql experience).

This is for a secure download service, where users login, choose a file and then download the file - however the file will come from a different server closer to them basically like a CDN system. So effectively there are three parts:

- Our Servers (PHP/mySQL)

- Client Web-Browser

- Server with end content (seperate location to the php/mysql - i.e. opposite sides of the country so we can't share access to the database/sessions etc) and may actually run on seperate virtual servers etc (PHP/mySQL and [url removed, login to view] versions)

So:

1) User goes to our website. Session is created - basic log details (username/password) and and a list of files are displayed.

2) User clicks on a file. It will then cause the browser to download the file from another server (each file in this version within the database lists the server it's on

3) Browser downloads File

Security:

However, we need it to be secure. We don't want other users to simply type in a URL to access the resources so we need some sort of security. I'm thinking, when the user requests the file the url for the redirect could have a transaction_id appended to it - and therefore when the file delivery server receives the request it will take the transaction_id, talk to our web-server via web services - REST?, say I've got this transaction_id for this file_id does this exist? If OK, the system will then delete the transaction_id from our database, allow the user to download it and then it's done.

Content/File Delivery Server:

- Has it's own database. This will list each file_id and then have a location for the file (such as file_id=1, location=D:\FileStore\1\[url removed, login to view]"
