llHTTPResponse

Summary

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

348	Function ID
0.0	Forced Delay
10.0	Energy

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.
• The response by default has "content-type: text/plain". Use llSetContentType to optionally return a different type, like "text/html".
