RequestURL

llRequestURL

Summary

Function: key llRequestURL( );

0.0	Forced Delay
10.0	Energy

Requests one HTTP:// url for use by this script. The http_request event is triggered with the result of the request.
Returns a key that is the handle used for identifying the result in the http_request event.

Caveats

• 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.
• The number of available URLs is a limited resource, that is to say, a script can only have so many open URLs. See LSL http_server#Resource Limitations for details.
• When abandoning a URL, always release it with llReleaseURL, otherwise it will leak.

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.

This script requests a new URL after region restart: <lsl> string url; key urlRequestId; key selfCheckRequestId;

request_url() {

   llReleaseURL(url);
   url = "";

   urlRequestId = llRequestURL();

}

throw_exception(string inputString) {

   key owner = llGetOwner();
   llInstantMessage(owner, inputString);

   // yeah, bad way to handle exceptions by restarting.
   // However this is just a demo script...

   llResetScript();

}

default {

   on_rez(integer start_param)
   {
       llResetScript();
   }

   changed(integer change)
   {
       if (change & (CHANGED_OWNER))
       {
           llReleaseURL(url);
           llResetScript();
       }

if (change & (CHANGED_REGION
