I have a script on my server that backs up files every 12 hours and stores them in a protected web directory. I have no problem making connection to the directory, checking for new backups, and downloading them.. At the same time the backup occurs, I have a php script run and update the backup version file and the vb app downloads the latest backup according to that.
What I would like to be able to do is somehow have my application listen for a command or even a single packet sent from my PHP script or server itself to initiate downloading the backups. Is this possible? What will I need to do?
