How to make a sub-domain point to a sub-directory using URL Rewrite

Using URL rewrite to point a sub-domain to a sub-directory (For Linux Hosting Only)

Step 1: Create a .htaccess file with the file manager inside the public_html folder of your website.
Step 2: Add your desired sample to the .htaccess file.

Manual redirection for all domains and sub-domains
This .htaccess file sample will direct all domain names and sub domains to folder names that you specify.

1. Use this sample if you have multiple domain names that you want to direct to the same folder.
2. Use this sample if you want to direct your domains to folders with names other than mydomain.com and subdomain.mydomain.com
3. You will need to make a separate entry for each of your domains in your .htaccess file

RewriteEngine on

#Fix missing trailing slash character on folders.
RewriteRule ^([^.?]+[^.?/])$ $1/ [R,L]

#www.domain.com and domain.com will map to the folder {root}/folder1/
RewriteCond %{HTTP:Host} ^(?:www\.)?domain\.com$
RewriteCond %{REQUEST_URI} !^/folder1/
RewriteRule ^(.*) folder1/$1 [NC,L,NS]

#www.otherdomain.com and otherdomain.com will map to the folder {root}/folder2/
RewriteCond %{HTTP:Host} ^(?:www\.)?otherdomain\.com$
RewriteCond %{REQUEST_URI} !^/folder2/
RewriteRule ^(.*) folder2/$1 [NC,L,NS]

#subdomain.domain.com will map to the folder {root}/folder3/
RewriteCond %{HTTP:Host} ^(?:subdomain\.domain\.com)?$
