There are plenty of scripts out there that require you to request a page on a daily basis to perform certain tasks. Normally you can accomplish this by setting up a simple cron. And on a good host, that’s easy. But what if your host doesn’t have cron? Well if you run WordPress, you now can use my Hit an External Cron plugin. You can download it from Google Code. It’s a simple plugin that adds an options page under settings to enter the url you need to visit on a daily basis.
Not only am I releasing this plugin under the GPL, but if you continue reading I’ll explain to you everything under the hood.
