What I need is this:
- I need to be able to insert a script into web pages that call a PHP file on my server.
Then I should have a simple control panel on my server where I can see all remote websites that call a file on my server.
In this control panel I should be able to select any of these remote website, and activate the file called on my server. This file could have exit() in it or something, resulting the remote website not to load the page.
This would be to control customers that are not paying for the website design and allows me to turn off their website. If you have a better way, let me know!
