.htaccess rewrite subdomain to directory

Is it possible to use .htaccess to rewrite a sub domain to a directory?

Example:

• http://sub.domain.com/

shows the content of

• http://domain.com/subdomains/sub/

Try putting this in your .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub.domain.com
RewriteRule ^(.*)$ /subdomains/sub/$1 [L,NC,QSA]

For a more general rule (that works with any subdomain, not just sub) replace the last two lines with this:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ subdomains/%1/$1 [L,NC,QSA]

I'm not a mod_rewrite expert and often struggle with it, but I have done this on one of my sites. It might need other flags, etc., depending on your circumstances. I'm using this:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteCond %{REQUEST_URI} !^/subdomains/subdomain
RewriteRule ^(.*)$ /subdomains/subdomain/$1 [L]

Any other rewrite rules for the rest of the site must go afterwards to prevent them from interfering with your subdomain rewrites.

You can use the following rule in .htaccess to rewrite a subdomain to a subfolder:

RewriteEngine On

 # If the host is "sub.domain.com"
 RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]
 # Then rewrite any request to /folder
 RewriteRule ^((?!folder).*)$ /folder/$1 [NC,L]

Line-by-line explanation:

  RewriteEngine on

The line above tells the server to turn on the engine for rewriting URLs.

  RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]

This line is a condition for the RewriteRule where we match against the HTTP host using a regex pattern. The condition says that if the host is sub.domain.com then execute the rule.

 RewriteRule ^((?!folder).*)$ /folder/$1 [NC,L]

The rule matches http://sub.domain.com/foo and internally redirects it to http://sub.domain.com/folder/foo.

Replace sub.domain.com with your subdomain and folder with name of the folder you want to point your subdomain to.

I had the same problem, and found a detailed explanation in http://www.webmasterworld.com/apache/3163397.htm

My solution (the subdomains contents should be in a folder called sd_subdomain:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} subdomain\.domain\.com
RewriteCond $1 !^sd_
RewriteRule (.*) /sd_subdomain/$1 [L]

This redirects to the same folder to a subdomain:

.httaccess

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://domain\.com/subdomains/%1
