Thanks, but this description sounds as if you're asking for a new feature/change. We use this tracker for bugs and issues only, we put ideas to work on in the future in the TODO document. We basically drown in good ideas so they don't do much use in our tracker.
If you really want to see this happen, start working on an implementation and submit a PR for it or join the mailing list and talk up more interest for it and see what help from others you can get!
OK. Well for --random-wait my reason is the same as wget's (see their man page.)
And for --wait: a curl command might send a million requests. I want a
few seconds/minutes between each request, while testing, for me to make sure
nothing went nuts, on my end, the network, or the remote server.
Sure, I could make a shell script
for u in URL1 URL2 URL3...
(But that might not always work the same as what we are hoping the single
curl run would do.)
