Summary

Function: integer llGetFreeURLs( );

Returns an integer that is the number of available URLs. If attached, return the URLs remaining for the owner. Otherwise, return the available URLs for the region.

Specification

There is a separate URL limit for the region, and a limit for each agent. The URL limit is the same as the Land Impact limit:

  • Agent: 38
  • Openspace Sim: 1,250
  • Homestead Sim: 5,000
  • Full Sim: 20,000
  • Mainland Sim: 22,500
  • 30k Sim: 30,000

Caveats

  • If called from an attachment, there is no way to get the number of free URLs in the region; it will always return the URL count remaining for the agent.

Examples

This script will say the number of currently available HTTP-In URLs left in the region.

default
{
    touch_start(integer num_detected)
    {
        integer numberOfFreeURLs = llGetFreeURLs();

        if (numberOfFreeURLs)
        {
            llSay(0, "There are " + (string)numberOfFreeURLs + " available HTTP-In URLs left in this region.");
        }
        else
        {
            llSay(0, "WARNING: There are no HTTP-In URLs available anymore.");
        }
    }
}
// WARNING:
//
//      This script is only for proof-of-concept (demo purposes).
//      DO NOT use it if you don't have the sim owners and/or
//      estate managers OK to test this script.
//      This script can possibly block HTTP communication from and to the sim.
//      ...bringing down all networked vendors and/or similar machines.
//
//      This script allocates all available URLs.
//      Deleting the script and/or derezzing the object containing the script,
//      will release all previously taken URLs.

    }
}

Notes

URLs are a finite region resource and should be released when no longer needed.
