Curl Extension

Maurits, CURL is akin to Lynx, in that it is a console / text mode app… It allows languages such as PHP to retrieve web pages, from remote hosts, or otherwise execute code, such as a maintance script for an advertisement service or such, that is being called through cron (some are designed to be standalone, others run via CURL, due to the way they send their output back), so end users can get error reports, etc…

It is commonly installed on Linux based webhosts, but whether you can access it or not, is dependent on your hosting provider. The best I can say is drop an email to your server admin, and see if it’s accessible, and if you need a specific path to access it or such…
