problem with redirecting to HTTPS automatically (Apache Users)

Hi,

i'm using XAMPP on my linux notebook for local dev.

my first step was to create a folder to store my web application and to check that if user does not use HTTPS, he will be redirected to the same page but with HTTPS.

i know that it can be done using mod_rewrite but i was not able to make it works correctly.

In fact, since first page i want to force users to be under HTTPS.

so here is my virtualhost conf file:

DocumentRoot "/opt/lampp/htdocs/jobportal-admin/"

ServerName www.jobportal-admin.loc

ServerAlias jobportal-admin.loc

ErrorLog "logs/jobportal-admin.loc-error_log"

CustomLog "logs/jobportal-admin.loc.com-access_log" common

Options Indexes FollowSymLinks Includes ExecCGI

DirectoryIndex index.php

Options All

AllowOverride All

Require all granted

</Directory>

</VirtualHost>

DocumentRoot "/opt/lampp/htdocs/jobportal-admin/"

ServerName www.jobportal-admin.loc

ServerAlias jobportal-admin.loc

Options Indexes FollowSymLinks Includes ExecCGI

DirectoryIndex index.php

SSLEngine on

SSLCertificateFile "/opt/lampp/etc/ssl.crt/server.crt"

SSLCertificateKeyFile "/opt/lampp/etc/ssl.key/server.key"

ErrorLog "logs/jobportal-admin.loc-error_log"

CustomLog "logs/jobportal-admin.loc.com-access_log" common

Options All

AllowOverride All

Require all granted

</Directory>

</VirtualHost>

and in my .htaccess i have the following:

RewriteEngine On

RewriteCond %{HTTPS} !=on

RewriteCond %{HTTP_HOST} ^www.jobportal-admin\.loc/ [NC]

RewriteRule ^(.*)$ https://www.jobportal-admin.loc/$1 [R,L]

but nothing is redirected to https :(

Any help would be appreciated.

thx a lot.
