I set up my CMS to open a small window that called up a script that sent pings in the background. I had also set up a script that sniffed out if the browser was blocking pop up windows for my CMS and asked the user to remove the block, but now, since I've changed comps, it seems that my damn anti virus is blocking it and won't let me change the settings!
Is there any other way, maybe a temp cron, that I could run a script in the background and still allow the user to surf away?
