This guide explains how to force the display of the web hosting name in the browser's address bar to one of the domain names installed as an alias/synonym or how to display the main domain in the address bar instead of the alias.

Limit the "duplicate content" or duplicate content

Suppose you have the hosting votre-domaine.com at Infomaniak and that as an alias domain name you have installed www.domainesyno.xyz.

By default, when you type either of the domain names (votre-domaine.com or domainesyno.xyz) in your browser's address bar, the one you typed will be displayed in the address bar.

You therefore have the possibility to force the display of a different address than the one that was typed. So if someone types domainesyno.xyz, then it is votre-domaine.com that will automatically appear in the address bar.

A code must be entered into a file called .htaccess which must be located at the root of your hosting (in the /web folder of your FTP). If this file does not yet exist, you must create it on the server.

Then insert these directives into the file:

RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://votre-domaine.com/$1 [R=301,L]

Adjust the code above according to these instructions:

• Replace votre-domaine.com with your domain name with the appropriate extension (.com, .fr, .ch, etc.) that you want to display in the browser's address bar for the visitor. Add www. before your-domaine.com if necessary.
• Replace the second line of the code above with "RewriteCond %{HTTPS} off‍" if a loop error occurs, this means that HTTP/2 is active for this site

Also, familiarize yourself with the automatic redirections to https.
