Tom McFarlin did this great series for WPTuts on the HTTP API:
- wp_remote_get – the Arguments
- wp_remote_get – the Response
- A Practical Example of wp_remote_get
- A Brief Survey of wp_remote_get
- A Practical Example of wp_remote_post
- Saving Data From wp_remote_post
If you’re using this for your plugins or themes you’re gonna probably rely on these pretty heavily (I know I did).
