NGINX cache decision explainer
Two different questions: will this response be stored, and will a later request be served from it. Paste the directives and the exchange to see both answers and why.
NetværkNGINX location matcher
Paste your location blocks and a URI, and watch NGINX's five-step selection run: exact, longest prefix, the caret-tilde early exit, regexes in file order, then the fallback.
NetværkNGINX proxy_pass rewriter
One trailing slash decides whether your backend sees /app/page or /page. Paste the directive and see both answers side by side.

Apache httpd: the server that ran the web, and the problem that produced NGINX
Apache began as patches to a server nobody was maintaining, and within a year it ran more of the web than anything else. The architecture that made it flexible is also the one that made it struggle under 2000s traffic, which is the problem NGINX was written to solve.
NetværkReadF5s hurtigere udgivelseskadence: månedlige hærdede udgivelser og sikkerhedsmeddelelser
Den 6. juli 2026 skiftede F5 fra en kvartalsvis til en månedlig sikkerhedskadence: hærdede softwareudgivelser den tredje onsdag hver måned fra den 15. juli, og sikkerhedsmeddelelser en måned senere fra den 19. august. Her står præcis, hvad der ændrede sig, hvorfor F5 siger, det ændrede sig, hvad der forbliver det samme, og hvad det betyder for, hvordan du patcher.
NetværkReadLimiting requests, connections and bandwidth in NGINX: leaky buckets and the burst that surprises people
Three different limits, three different directives, and one shared mechanism worth understanding before you tune it. The request limiter is a leaky bucket, not a quota per second, and burst plus nodelay change its behaviour in ways the names do not suggest.
NetværkReadNGINX caching: what gets stored, what gets served, and the gap where user data leaks
Whether a response is stored and whether a later request is served from it are different questions with different answers. NGINX protects you from caching a cookied response, and does not protect you from serving a cached response to a cookied request. That asymmetry is where one user receives another user's page.
NetværkReadNGINX location matching: why the block you expected is not the one that ran
NGINX does not pick the first location that matches, and it does not pick the last. It follows a fixed five-step order in which the file's own order matters for exactly one step, which is why reading a config top to bottom will mislead you about which block wins.
NetværkReadReloading NGINX without dropping traffic, and the first four things to check when it breaks
A reload is not a restart: the master validates the new configuration, starts new workers, and lets the old ones finish what they were doing. Knowing that, and knowing which log answers which question, resolves most NGINX problems before they become interesting.
NetværkReadThe NGINX configuration tree: what includes, in what order, and who owns the worker
One file, a directory of fragments, and an include order that decides which directive wins. Plus the two ownership questions that explain most permission failures: which user the master runs as, which user the workers run as, and why those are deliberately different.
NetværkReadThe NGINX proxy_pass trailing slash: one character that decides what your backend receives
proxy_pass with a URI part replaces the matched location prefix. Without one, the original request URI passes straight through. That is the entire rule, it is a binary switch rather than a shade of difference, and a single slash is enough to flip it.
