How to write a subdomain with htaccess?

I am trying to make a subdomain forward through the htaccess document. The below instructions will forward http://sub.domain.com to the internal structure Root > subfolder > index.php. This all works well.

# REWRITE DEFAULTS
# ====================================================================================================
RewriteEngine On
RewriteBase /

# SUBDOMAIN FORWARD
# ====================================================================================================
RewriteCond %{HTTP_HOST} ^sub.domain.com$ 
RewriteRule ^(/)?$ subfolder/index.php [L]

RewriteCond %{HTTP_HOST} ^sub.domain.com$ 
RewriteCond %{REQUEST_URI} !^/subfolder/
RewriteRule ^(.*)$ /subfolder/$1

There is only one (big) downfall with this method. When you try to reach a folder within the subfolder such as Root > subfolder > images by going to http://sub.domain.com/images/ then all works well again, however when you don't end it with a slash http://sub.domain.com/images the url in the address bar will become http://sub.domain.com/subfolder/images/ which is clearly not what I want.

So what if I would add a slash if a slash was forgotten?

RewriteCond %{HTTP_HOST} ^(.*).domain.com$ 
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteCond %{REQUEST_FILENAME} !(.*)/$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ http://%1.domain.com/$1/ [L,R=301]

This all works when you have a normal URL (http://www.domain.com/images), because it will detect it is a directory and adds a slash and if it's a file it will omit the slash. However this does not work for our http://sub.domain.com/images example.

Does anyone have an idea how you can make subdomains work properly using htaccess?

That is happening because /subfolder/images is a real directory and mod_dir module adds a trailing slash to all directories by doing a 301 redirect.

You can use it like this:

RewriteEngine On

# add a trailing slash if /subfolder/images is a directory
RewriteCond %{HTTP_HOST} ^sub\.domain\.com$ [NC]
RewriteCond %{DOCUMENT_ROOT}/subfolder/$1/ -d
RewriteRule ^(.*?[^/])$ %{REQUEST_URI}/ [L,NE,R=302]

RewriteCond %{HTTP_HOST} ^sub\.domain\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/subfolder/
RewriteRule ^(.*)$ /subfolder/$1 [L]
