If SSL Is Installed on the server and we can redirect all the request to https. One method to do Is configure the .htaccess file. We can achieve this by adding following code to the .htaccess file
===================
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]===================
Or we can use the code as follow
===================
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ https://www.domain.com [L,R]====================
That's it now all the request coming to the domain will be redirected to the https.
