How to Force HTTPS on All Traffic using .htaccess

Force HTTPS on All Traffic – After installing an SSL certificate, your website is available over HTTP and HTTPS. However, it’s better to use only the latter because it encrypts and secures your website’s data. While NeueHost allows users to configure this setting in just one click, you can also use the .htaccess file to force an HTTPS connection. This tutorial will show you how.

Force HTTPS on All Traffic

One of the many functions you can perform via .htaccess is the 301 redirects, which permanently redirects an old URL to a new one. You can activate the feature to force HTTPS on all incoming traffic by following these steps:

1. Go to File Manager in your hosting panel and open .htaccess inside the public_html folder.
2. Scroll down to find RewriteEngine On and insert the following lines of code below it:

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

3. Save the changes.

Force HTTPS on All Traffic on a Specific Domain

Let’s say that you have two domains:
http://yourdomain1.com and http://yourdomain2.com. Both domains access the same website, but you only want the first one to be redirected to the HTTPS version. In this case, you need to use the following code:

RewriteEngine On 
RewriteCond %{HTTP_HOST} ^yourdomain1.com [NC] 
RewriteCond %{HTTPS} off 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Forcing HTTPS on a Specific Folder

The .htaccess file can also be used to force HTTPS on specific folders. However, the file should be placed in the folder that will have the HTTPS connection.

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteRule ^(folder1|folder2|folder3) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Make sure to change the folder references to the actual directory names.

After making the changes, clear your browser’s cache and try to connect to your site via HTTP. If everything was added correctly, the browser will redirect you to the HTTPS version.

Conclusion

Congratulations! you have successfully edited your .htaccess file and redirected all HTTP traffic to HTTPS, the safe version of your website. Depending on the platform where you developed your website, there could be alternative methods to enable this feature.
