Redirect from http to https using htaccess

Some case you want that only some of the pages to redirect to https but not all pages.

In that case the code in above post will not work hence it will redirect all pages to https.

To redirect only some of the pages you need to use below code in your htaccess file.

RewriteEngine on

RewriteCond %{HTTPS} off

RewriteCond %{REQUEST_URI} order.php [OR]

RewriteCond %{REQUEST_URI} payment.php [OR]

RewriteCond %{REQUEST_URI} success.php

RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

From above code in your website only order.php, payment.php and success.php will be redirect to https protocol.

Here I have used RewriteCond with OR condition. If we use OR condition than Rule will be apply if any of the condition gets true. For more detail about OR condition
