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 result of the request. HTTPS-in uses port 12043.
Returns a handle (a key) used for identifying the result of the request in the http_request event.
Caveats
- HTTPS-in uses port 12043.
- When a region is (re)started all HTTP server URLs are automatically released and invalidated.
- Use CHANGED_REGION_START to detect this so new URL can be requested.
Examples

Important: Never ever forget to release a URL again which you have requested! URLs are region resources just like prims. If you take them all you can get into big trouble with the sim owner and/or estate managers. |
