Summary

Function: llHTTPResponse( key request_id, integer status, string body );

Responds to request_id with status and body.

• key request_id A valid HTTP request key.
• integer status HTTP Status (200, 400, 404, etc)
• string body Contents of the response.

The response need not be made inside the http_request event but if it does not happen in a timely fashion the request will time out (within 25 seconds).

Caveats

  • This call must be made by the script containing the http_request event where the request_id was received.
  • There is no limit, other than script size, to the amount of data that can be sent by this function.
    • llHTTPRequest can truncate the response length in receiving scripts. Be aware when using them together for prim-to-prim communications.
  • Returns 'content-type: text/plain' by default. Use llSetContentType to optionally return 'text/html' if being viewed by the object owner within a Second Life client.
