Call website / remote script after upload

I am currently working on an automatic data-update process which involves 3 steps:

1. Export data from our local software (this is being done every 30 minutes automatically)
2. Upload these files to our FTP server (I'm using the SmartFTP monitoring function for this, works very well)
3. Execute a PHP-script on the server which will use the uploaded files to update the website

Currently number 3 is a problem: I don't know how to do it. I tried to make a javascript with post-transfer actions but it didn't work for some reason.

So how can I open a website ( after a certain transfer is complete? To make it clear: I don't have to see this website, it just has to be executed / requested or however you wish to call it.

I hope you understand what I am trying to do

Edit: Just in case you need to know it, here's my system config

+- System -----------------------------
Microsoft Windows 7
(Build 7600)

CPU Speed : 2601 MHz

Yes this can be done with a post transfer script.

Never mind I got it working

I just had an error in my javascript file.

Thank you anyway!
