HTTP 429 Too Many Requests from Nginx

[vorburger]

I toyed around with some "load testing" (using the test CID URL from #124/#142), and found that:

ab -n 10000 -c 2 http://192.168.1.xxx:31080/ipfs/QmXjYBY478Cno4jzdCcPy4NcJYFrwHZ51xaCP8vUwN9MGm/

works great and has Failed requests: 0. But if I crank up the concurrency (the -c) just one notch from 2 to 3, it will soon fail with HTTP 429 = Too Many Requests (from Nginx), and have e.g. 996 Failed requests (for me).

Is this expected? Maybe it's totally fine, and exactly Working As Intended (WAI); I'm just wondering.

#143 COULD be related and relevant for this? If Nginx can't tell HTTP clients apart, will this happen IRL?

https://www.nginx.com/blog/rate-limiting-nginx/ has some background about this stuff (I haven't fully read it, yet).

This is intended and it's a very basic anti ddos measure
