Notes

If for some reason while using llHTTPRequest/http_response you are unable to parse a known good RSS feed or some other form of web contents, you will need to work around it outside of SecondLife. This is unlikely to change in the near future since checking the headers requires more overhead at the simulator level.

Status 499 is never returned by a website in response to an llHTTPRequest call. This status indicates that the request timed out and the sim closed the connection before any response was received.

Some useful HTTP headers sent are:

• HTTP_X_SECONDLIFE_LOCAL_POSITION
• HTTP_X_SECONDLIFE_LOCAL_ROTATION
• HTTP_X_SECONDLIFE_LOCAL_VELOCITY
• HTTP_X_SECONDLIFE_OBJECT_KEY
• HTTP_X_SECONDLIFE_OBJECT_NAME
• HTTP_X_SECONDLIFE_OWNER_KEY
• HTTP_X_SECONDLIFE_OWNER_NAME
• HTTP_X_SECONDLIFE_REGION
• HTTP_X_SECONDLIFE_SHARD
