Auto Refresh Website program/script with Proxy support

I'm looking for a program or script that lets me autorefresh a page of a website. I already have an autorefresh plugin for Mozilla FireFox but it does not have proxy support! The goal of the program/script is to manipulative increase the amount of views on my advertisements on various websites. The amount of views are only counted with unique IP's so thats why I need an autorefresh with Proxy support. If you can develop one for Mac OS X it will be a big plus and I pay you more but Windows XP is also fine.
