Hi everyone, hoping someone here can point me in the right direction.
I'm writing a couple of php scripts for creating temporary urls for file downloads.
Here's how it works, sort of...
There are 2 files: generate.php & download.php
generate.php creates a hash that references the file to be downloaded.
Then, when the hash is passed to download.php like so...
download.php?hash=thehashstring
The file is fed to the browser.
No problem so far. Here's the catch...
I need to call generate.php from a script on a completely different server, something like this...
Master Script on Server A calls generate.php script on Server B...A new hash is returned to the Master Script on Server A by generate.php on Server B...Master Script on Server A then ouputs the download url using the newly generated hash.
I'm a bit unclear just how one goes about this in php -- having 2 scripts talk to each other on different servers. Also, I will need to set this up in such a way so that it is relatively secure. IOW, generate.php will only generate and return a new hash if it is being called by the Master Script on Server A. (If it is called from a different server, or directly through a browser, then it wont generate a new hash.)
Any suggestions as to how to best achieve this would be much appreciated.
Cheers!
