=== Making HTTP Requests via Nasal === | |||
FlightGear versions >= 2.8 include a new feature to make HTTP requests using a new xmlhttprequest fgcommand. So, Nasal is able to execute so called "fgcommands", these are internal FlightGear commands implemented in C++ This can be used to implement AJAX-like server/client exchanges. | |||
You can pass any FG property tree data (lat,lon,alt,groundspeed etc) via conventional GET requests. | |||
The request will be made asynchronously, in order not to block the main loop and affect the frame rate. This is why you should register a listener to invoke a callback upon completion of the request and check the status flag (200=OK). | |||
For further details, please see [[Howto:Making HTTP Requests from Nasal]]. | |||
