How to enable redirection from HTTP to HTTPS for a domain in Plesk

1. Log in to Plesk.
2. Go to Domains > example.com > Apache & nginx Settings.
3. Copy the following directives to the Additional directives for HTTP field:

   Note: If you are a domain owner and Apache & nginx Settings is not available for you, please contact your service provider for assistance with permanent HTTPS redirection.

   <IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{HTTPS} !=on
   RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R,QSA]
   </IfModule>

4. Copy the following directives to the Additional nginx directives field, if nginx is used:

   if ($ssl_protocol = "") {
   rewrite ^/(.*) https://$server_name/$1 permanent;
   }

Note: This solution is applicable only if a website is processed by Apache.

1. Log in to Plesk.
2. Go to Domains > example.com > File Manager.

   <IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteCond %{HTTPS} !=on
   RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R,QSA]
   </IfModule>

   <rewrite>
   <rules>
   <rule name="HTTP to HTTPS redirect" stopProcessing="true">
   <match url="(.*)" />
   <conditions>
   <add input="{HTTPS}" pattern="off" ignoreCase="true" />
