Force WordPress to use SSL: When youre using SSL on your WordPress-powered website youll know that simply changing your websites url in the setting isnt enought, it will redirect the homepage to your HTTPS version, but when a user goes to example.com/blog it wont redirect to HTTPS, this can cause trouble with including stylesheets etc. Now, you can use a plugin to fix this but if youre like me and dont want to use plugin unless absolutely necessary you can do this yourself.

Without a plugin

.htaccess

Simply add the following code to your .htaccess file will make it work.

# BEGIN WordPress
 RewriteEngine On
 RewriteCond %{HTTPS} !=on
 RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]
 RewriteRule ^index.php$ - [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
 # END WordPress

Javascript

Or you can add the following piece of Javascript to your site.

<script>
if (document.location.protocol != "https:") {
    document.location = document.URL.replace(/^http:/i, "https:");
}
</script>

With a plugin

Ofcourse you can also use a plugin to do this for you, I myself use Really Simple SSL and would highly recommend it.
