I believe one of the worst-case scenarios from XML-RPC today is the InnerLife / Mandala Web Temple architecture. Last I experimented (with an early format) we got stable results at 4 second intervals (this was back in mid-2006); We wanted faster (not enough for a proper biofeedback interface) so most dropped the project. Be aware that we wanted something that could be sustained for long intervals (3-4 hours straight, possibly with multiple avatars contributing toward 'merged' results). I'm not certain what the current request load is today, you can check with 'Carlos Tapioca' in-world as he is still actively perusing this. I'll also direct him here.

I think there should be a URL_REQUEST_TIMEOUT method. That way the script has a chance to catch the event and send the user some meaningful information before the connection actually cut. A user could have two scripts, one that handles the HTTP serving while the other gathers data. If the data gathering sends the data as it receives it then the HTTP script can cache the data and when it receives all of it or the timeout is thrown it can send the data it has. If the script misses the window on the connection and the event was queued then it should be dequeued and not triggered. -- Strife Onizuka 16:53, 16 May 2008 (PDT)
- There are no plans for such an event. Requests will time out which will send a timed out error / status (504 Gateway Timeout) to the requester. Events are a scarce resource in LSL, also anything that lets you do 'one last thing' before a time out either creates a time out loophole or is already too late. If you find your requests are frequently timing out you will need to adjust your code to return smaller result sets more frequently. - Kelly Linden 10:55, 13 June 2008 (PDT)
Might be beneficial to have HTTP_STATUS_* code constants. -- Strife Onizuka 20:34, 16 May 2008 (PDT)
- Specifically which codes do you want defined this way? I'd like to keep the number of constants to a minimum, would _OK (200), _MISSING (404) and _ERROR (500) be enough? - Kelly Linden 10:47, 13 June 2008 (PDT)
- Those sound good. -- Strife Onizuka 11:42, 13 June 2008 (PDT)
Do we want google spidering the caps urls? -- Strife Onizuka 20:34, 16 May 2008 (PDT)
- This is a good point, and probably not. - Kelly Linden 10:56, 13 June 2008 (PDT)
Payload Size Limits / Content
Will the data payload size be similar to the current http_response limits? And will we be able to implement something like reverse http with it?
What about the content-type and more importantly charset? Will it be utf-8? Are URLs in utf-8? Is it "text/plain; charset=utf-8" then? - Thomas Shikami 20:31, 16 June 2008 (PDT)
