# Nginx Proxy Memory Leak Reproduction

To cause the reported memory leaks with nginx 1.24.0, do the following:

1. Setup a web-host, which serves /index.html (or use just any)
2. Ensure that this server has a valid TLS certificate and supports TLS1.3
3. Setup an OpenBSD 7.4, apply syspatch, install nginx-1.24.0p0 from packages.
4. Generate a TLS certificate for the host and adjust the supplied `nginx.conf`,
   pointing the proxy pass at the host setup in 1. and referencing the hosts'
   certificate instead of the example.
5. Use the script in scraper.py to issue HTTP requests from a third host. See
   README.md there for more details.
