Please help me to sort out this. Thanks in advance.

Answer 1

You have two choices.

1. Either you add a condition in your file to only match main domain

Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^example\.com$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Note that the rule to match www main domain can be removed since your main domain is example.com (no trace of www in your vhosts).

Warning: useless in some cases, you should not include the same file in all vhosts (see next point).

2. Or you can directly put a rule in example.com (http) vhost block. Indeed, others two ( example.com for https and stagging subdomain) do not require rules to do what you want.

So, your config should look like this

<VirtualHost *:80>
ServerAdmin  test@example.com
ServerName   staging.example.com
ServerAlias  staging.example.com
SetEnv       ENVIRONMENT staging
DocumentRoot /var/www/staging/
ErrorLog     /var/log/apache2/example_staging_error.log
CustomLog    /var/log/apache2/example_staging_access.log combined

<Directory /var/www/staging>
</Directory>


</VirtualHost>

<VirtualHost *:80>
ServerAdmin  test@example.com
ServerName   example.com
ServerAlias  example.com
SetEnv       ENVIRONMENT production
DocumentRoot /var/www/production/
ErrorLog     /var/log/apache2/example_production_error.log
CustomLog    /var/log/apache2/example_production_access.log combined

<Directory /var/www/production>
Options +FollowSymlinks
RewriteEngine On
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</Directory>



</VirtualHost>
LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl.so
#Listen 443
<VirtualHost *:443>
