Force HTTPS Redirects with .htaccess

· Eric Ma · updated April 13, 2026

Forcing HTTPS on your website protects visitor data and improves SEO. The most common method is using .htaccess with Apache’s mod_rewrite module to redirect all HTTP requests to HTTPS.

Basic HTTPS redirect

Add this to your .htaccess file in the document root:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This performs a permanent 301 redirect from HTTP to HTTPS. The conditions and rules work as follows:

The [L,R=301] flags mean:

Alternative: redirect specific domains

If your site uses multiple domains or subdomains, you can be more selective:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

The [NC] flag makes the domain match case-insensitive.

Forcing HTTPS with www prefix

To ensure visitors always use www.example.com over HTTPS:

RewriteEngine On
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule ^ https://www.example.com%{REQUEST_URI} [L,R=301]

This handles three cases: HTTP without www, HTTPS without www, and HTTP with www — all redirect to https://www.example.com.

Removing www while forcing HTTPS

To enforce https://example.com (no www):

RewriteEngine On
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^ https://example.com%{REQUEST_URI} [L,R=301]

Prerequisites and testing

Before deploying this in .htaccess:

  1. Verify mod_rewrite is enabled — check with your hosting provider or run apache2ctl -M | grep rewrite on your server
  2. Ensure your SSL certificate is installed — test at https://yoursite.com to confirm the certificate loads without errors
  3. Test the redirect — use curl -I http://yoursite.com to verify it returns a 301 response
  4. Check for mixed content — after enabling HTTPS, audit your site for resources (images, scripts, stylesheets) still loading via HTTP

Why 301 redirects matter

A 301 redirect signals to browsers and search engines that the move to HTTPS is permanent. Search engines will update their index and transfer SEO ranking from HTTP to HTTPS. Temporary redirects (302) will not achieve this and may confuse caching layers.

HSTS headers for added security

After HTTPS is working, consider adding HSTS (HTTP Strict Transport Security) to your .htaccess:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

This tells browsers to always use HTTPS for your domain, even on the first visit. The max-age value is in seconds (31536000 = 1 year).

Common issues

Infinite redirect loop — ensure your SSL certificate is valid and installed. An invalid cert can cause the server to reject HTTPS, creating a loop.

Not working at all — mod_rewrite may be disabled, or .htaccess files may not be processed (check AllowOverride All in your Apache configuration).

Slow redirects — 301 redirects are cached aggressively by browsers. If you need to test multiple times, use incognito/private mode or clear your browser cache.

2026 Comprehensive Guide: Best Practices

This extended guide covers Force HTTPS Redirects with .htaccess with advanced techniques and troubleshooting tips for 2026. Following modern best practices ensures reliable, maintainable, and secure systems.

Advanced Implementation Strategies

For complex deployments, consider these approaches: Infrastructure as Code for reproducible environments, container-based isolation for dependency management, and CI/CD pipelines for automated testing and deployment. Always document your custom configurations and maintain separate development, staging, and production environments.

Security and Hardening

Security is foundational to all system administration. Implement layered defense: network segmentation, host-based firewalls, intrusion detection, and regular security audits. Use SSH key-based authentication instead of passwords. Encrypt sensitive data at rest and in transit. Follow the principle of least privilege for access controls.

Performance Optimization

Troubleshooting Methodology

Follow a systematic approach to debugging: reproduce the issue, isolate variables, check logs, test fixes. Keep detailed logs and document solutions found. For intermittent issues, add monitoring and alerting. Use verbose modes and debug flags when needed.

These tools complement the techniques covered in this article:

Integration with Modern Workflows

Modern operations emphasize automation, observability, and version control. Use orchestration tools like Ansible, Terraform, or Kubernetes for infrastructure. Implement centralized logging and metrics. Maintain comprehensive documentation for all systems and processes.
