How To Redirect To HTTPS And Enforce WWW Using .htaccess?

Published July 19, 2024

Problem: Redirecting to HTTPS and Enforcing WWW

Redirecting website traffic to HTTPS and enforcing the use of "www" in URLs improves website security and maintains consistent web addresses. The .htaccess file allows you to implement these redirects on Apache servers, but setting up the correct configuration can be difficult.

The Solution: Correcting Your .htaccess Code

Separating HTTPS and WWW Redirects

To fix the issue with your .htaccess file, separate the HTTPS and WWW redirects. This allows for better control over the redirection process.

Create a rewrite rule for HTTPS:

RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This rule checks if the connection is not using HTTPS and redirects it to the secure version if needed.

Add a separate rule for enforcing WWW:

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This rule checks if the URL doesn't start with "www" and adds it if needed. By separating these rules, you make sure that the HTTPS redirect happens before the WWW enforcement, avoiding conflicts.

Tip: Test Your Redirects

After implementing these changes, test your redirects using various URL combinations (http, https, www, non-www) to make sure they all lead to the correct https://www version of your site. You can use online redirect checkers or simply try accessing your site with different URL variations in your browser.

Implementing the Correct .htaccess Code

Step-by-Step Configuration

To implement the correct .htaccess code for redirecting to HTTPS and enforcing WWW, follow these steps:

  1. Set up RewriteEngine: Start by enabling the RewriteEngine in your .htaccess file. Add this line at the beginning of your file:
RewriteEngine On

This activates the mod_rewrite module, allowing you to use URL rewriting rules.

  1. Write the HTTPS redirect rule: Add these lines to redirect HTTP traffic to HTTPS:
RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This rule checks if the connection is not using HTTPS and redirects it to the secure version if needed.

  1. Add the WWW enforcement rule: Include these lines to enforce the use of WWW in your URLs:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This rule checks if the URL doesn't start with "www" and adds it if needed.

Your complete .htaccess file should now look like this:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

This setup will redirect all traffic to the HTTPS version of your site and enforce the use of WWW in your URLs.

Tip: Test Your .htaccess Configuration

After implementing your .htaccess rules, it's important to test your configuration thoroughly. Try accessing your website using different combinations of HTTP/HTTPS and with/without WWW to make sure all scenarios redirect correctly. You can use online tools or browser developer tools to check the HTTP status codes and redirection paths.

Testing Your New Configuration

Verifying Redirects

After setting up the new .htaccess configuration, test your redirects to make sure they work correctly. Here's how to check the HTTP to HTTPS redirect and WWW enforcement:

Checking HTTP to HTTPS redirect:

  1. Open a web browser and enter your website's URL using "http://"; (e.g., http://yourwebsite.com).
  2. See if the browser redirects you to the "https://"; version of your site.
  3. Check the address bar to confirm that the URL starts with "https://";.

Confirming WWW enforcement:

  1. Access your website without the "www" prefix (e.g., https://yourwebsite.com).
  2. See if the browser redirects you to the version with "www" (e.g., https://www.yourwebsite.com).
  3. Check that the final URL in the address bar includes both "https://"; and "www".

To cover all scenarios, test these combinations:

All these variations should redirect to https://www.yourwebsite.com. If any of these tests fail, review your .htaccess file for errors or ask your web hosting provider for help.

Clear your browser cache before testing to avoid cached redirects affecting your results. You can also use online redirect checker tools for extra verification.

Tip: Use Command Line for Additional Testing

You can use the command line to test your redirects more thoroughly. Open a terminal and use the 'curl' command with the '-I' flag to check the HTTP headers:

curl -I http://yourwebsite.com

This will show you the response headers, including any redirect information. Look for a '301 Moved Permanently' status code and a 'Location' header pointing to your desired URL.
