Apache rewrite URL slug to subdomain

[Jonathan_bdlf]

Hey the community, I need you once again

 

There's something I couldn't wrap my head around with my web server... 

 

First things first, I'm running a Lightsail instance with a Lamp package using bitnami.

My title may seem a bit weird. To better understand it, here's what I'm aiming to do :

1. A user reaches domain.fr/blog

2. He's been internally redirected to blog.domain.fr

3. The address bar is still showing domain.fr/blog

That's something I was able to achieve by using this in the bitnami-ssl.conf under <VirtualHost default:443>

    ProxyPass /blog http://blog.domain.fr/    
    ProxyPassReverse /blog http://blog.domain.fr/  

So when I go to domain.fr/blog I can see the blog I'm setting up !

Now I've created myself two problems :

• If I reach blog.domain.fr I can access all of the content. Therefore, I have 2 canonical URLs for the same content, which is really bad for SEO.

• I can't access domain.fr/blog/login for instance...

 

So I'm asking you guys two questions :

1. How to redirect properly blog.domain.fr to domain.fr/blog

2. How to make it works properly i.e., /blog/login not showing 404 (blog.domain.fr/login is working)

One more precision : the blog I'm setting up is running using Laravel and Jetstream 

 

Here's what I tried to do :

I've added under the <Virtual Host *:443> for the blog vhost this line :

    RewriteEngine On
    RewriteRule ^ https://domain.fr/blog%{REQUEST_URI} [L,R=301]

I end up with the error TOO_MANY_REDIRECTS on both blog.domain.fr and domain.fr/blog

I'm not an Apache expert or whatsoever, please be kind !

 

Feel free to ask any questions if what I'm trying to achieve seems hard to understand
