Question 1

What is .htaccess?

Accepted Answer

A .htaccess file (Hypertext Access) is a distributed configuration file for the Apache HTTP Server that applies settings on a per-directory basis — ideal when you lack access to the main server config, such as on shared hosting. Common uses include HTTPS redirects, URL rewriting, caching headers, and access control. See the official Apache .htaccess guide.

Question 2

Required Apache modules

Accepted Answer

mod_rewrite — URL rewriting and conditional redirects. mod_deflate — GZIP compression for text responses. mod_expires — browser caching via Expires and Cache-Control headers. mod_headers — custom HTTP response headers. All 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.
