Question 1

O que é .htaccess?

Accepted Answer

.htaccess is a distributed server configuration file for Apache HTTP Server. It enables per-directory configuration without touching the main server config. Widely used on shared hosting for URL rewriting, redirects, security rules, and performance optimizations.

Question 2

Required Apache modules

Accepted Answer

mod_rewrite — URL rewriting and redirects. mod_deflate — GZIP compression. mod_expires — browser caching headers. mod_headers — custom HTTP response headers. These modules are enabled by default on most shared hosting providers.

Question 3

Common .htaccess rules

Accepted Answer

Force HTTPS — redirect all HTTP traffic to HTTPS using RewriteCond %{HTTPS} off and a 301 redirect. Essential for security and SEO. WWW redirect — canonicalize your domain to either www or non-www to avoid duplicate content. Custom 404 — serve a branded error page instead of the default Apache 404. Directory listing — disable with Options -Indexes to prevent exposing file structure to visitors.

Question 4

Performance optimization with .htaccess

Accepted Answer

GZIP compression reduces the size of HTML, CSS, JavaScript, and SVG responses by 60–80%, significantly improving page load times. Browser caching via mod_expires tells browsers to cache static assets (images, fonts, scripts) for weeks or months, eliminating redundant downloads on repeat visits. Combined, these two rules can reduce page load time by 50% or more on typical websites.
