Hi Dave, Thanks for your suggestion.
Loading the internal cache in the 'init_xxx()' routine is not fisable for my case, becaues my external data will be updated periodically. Also the loacl structure needs to be updated periodically. In my case, do you have any other suggestion? The time it took to get the external data is really much(about several minutes). So I still try to not get *all* the external data. If I can get the index values in an incoming request, I can just get one entry(row) from outside one time. Do you agree to this?

Why not load this internal cache in the 'init_xxx()' routine, rather than the get_first hook? You'll still have the same delay, but it will happen when the agent first starts up, rather then when it receives a request.
