[Resolved] Securely Access files from other server

[eluser]TheFuzzy0ne[/eluser]
I was trying to suggest that your users download the file straight from server 2, as transferring the file from one server to another could cause a slow down, especially if they aren't on the same local network. The way I had in in my mind, would work something like this:

Do whatever authentication you need to on server 1
Server 1 sends a request to server 2 containing the a key (an MD5 hash of the date with the microtime should be fine).
Server 1 redirects over to server 2, using the key in the URL
Server 2 validates the key against the database, and if it's valid, initiates the download, and removes the entry from the database (before the download starts). I'd also suggest a 30-60 second expiration on the keys, so if the download is not started, it's removed from the database.

Does that help you at all?
