This guide explains how‍ to create subdomains on an existing Infomaniak hosting using a .htaccess file.

Introduction

• The hosting can be on an offer of Shared Web Hosting or on Infomaniak Cloud Server but this function is impossible with a Starter hosting.
• Subdomains can be added very easily to your current hosting since you have in the basic offer 20 sites per hosting (sites = subdomains).
• If you do not want to use this site volume available to you, you can follow the method below.

Create a subdomain as a shortcut

The subdomains thus created make it easier to organize a hosting. For example the address vlog.domain.xyz will be the shortcut of the address domain.xyz/vlog. In other words, the address vlog.domain.xyz will redirect to the vlog folder which must be located at the root of the website domain.xyz. In this example, vlog is the subdomain of domain.xyz.

1. Add the subdomain as an alias of your website

To do this:

1. Follow the procedure for adding an alias but please read the points 2 and 3 below.
2. In the field to add the related domain, enter the full address of the subdomain (for example vlog.domain.xyz).
3. If your domain or its DNS zone is managed at Infomaniak, activate the following two options: Update DNS entries for this domain and Replace existing entries ; if this is not the case, create a A record with your registrar with the following information:
   • field: the full URL of the subdomain (for example vlog.domain.xyz)
   • target: the IPv4 address (A record) of your site (refer to this other guide to find the A record of your site)

2. Modify the .htaccess file of your website

Using your FTP software/client or Web FTP on the Manager, add and adapt the following code in the .htaccess file located at the root of your website:

RewriteCond %{HTTP_HOST} ^(.*)\.domain\.xyz [NC]
RewriteCond %{DOCUMENT_ROOT}/%1/ -d
RewriteCond %1::%{REQUEST_URI} !^(.*?)::/\1/?
RewriteRule "^(.*)$" "%{DOCUMENT_ROOT}/%1/$1" [L]

Replace on the first line:

• domain with your domain name
• xyz with your domain extension (ch, fr, etc.)

Now, the address vlog.domain.xyz should display the content of the vlog folder located at the root of your website. If this is not the case, check that the vlog folder exists at the root of your website.
