问题
I am not sure if this is the correct forum to ask this but i am not sure where to ask either. So here is my question:
what does "deep ping" mean. I tried google but still did not get any information about it. Also who does deep ping mean in web servlet`s context. Thanks.

I'm not sure it's the "official definition" if there is such a thing, but I've head "deep ping" used about functionality that allows you to (in contrast to a regular ping) send a message to the server that passes through as much of the webstack as possible before returning an "ok" response.
As an example, you can make a ping transaction that passes from the network straight down the stack to the database and there does a dummy select to read the ok from a dummy table and return that result. That allows you to (in contrast to a "normal ping" that tests only the network) have confidence that all layers in the application including the database are actually alive.

- Ping is one of the most basic and useful network commands. It sends request to networked computer and waits for response. It’s easy to ping single PC but it’s pain to ping dozens (or even hundreds) of them.
- The process of Pinging the entire Subnet which can have N nos of PCs are known as Deep Ping. Network scanners are usually used to do this....
