Summary

Function: key llRequestSecureURL( );
0.0 Forced Delay
10.0 Energy

Requests one HTTPS:// (SSL) url for use by this object. The http_request event is tiggered with results.
Returns a key that is the handle used for identifying the request in the http_request event.

Caveats

  • When a region is (re)started all HTTP server URLs are automatically released and invalidated.

Examples
