production checklist for avoiding duplicate content in large sites in nginx performance

a reliable nginx performance setup is less about clever code and more about repeatable habits. in this guide, we look at avoiding duplicate content in large sites during a production cleanup and keep the steps focused on production work.

security and maintenance notes

avoid mixing content decisions with infrastructure decisions. templates, query rules, and cache behavior should be separate enough that changing one does not unexpectedly break the others.

security hardening works best as a checklist. confirm permissions, secrets, headers, upload limits, and logging. do not hide security settings inside unrelated code because future reviewers will miss them.

location / {
    try_files $uri $uri/ /index.php?$args;
}

implementation checklist

• run linting
• run unit tests
• run one integration check
• verify staging config
• tag the release

final notes

the best result is not only a faster or cleaner nginx performance implementation. it is a change that another developer can inspect, understand, and safely repeat. keep the final commands, metrics, and assumptions close to the article so future maintenance is easier.
