How can I change all subdomains to read different content from their respective subdirectories?

I have my DNS configured to accept any subdomain (wildcard *), but I am having trouble feeding back the required content to the browsers.

I would like each subdomain to return the relative content, which resides in subdirectories of the same name within the public_html path of my server.

eg, example.domain.com/picture.jpg would actually request the file at public_html/example/picture.jpg

Currently I have tested the followed .htaccess code, but it is not functional:

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

This code, and similar tests, can redirect based on the su开发者_运维百科bdomain (%1) fine, but the request string ($1) seems to be the issue.

Maybe you could take a look at the mod_vhost_alias module :

http://httpd.apache.org/docs/2.0/mod/mod_vhost_alias.html

Try the following:

    RewriteCond %{HTTP_HOST} ^([0-9a-z-]+).domain.com [NC]
    RewriteRule ^/(.*) http://domain.com/%1/$1 [L]

I didn't test this one but I use similar rules for proxying:

RewriteCond %{HTTP_HOST} !^domain.local [NC]
RewriteCond %{HTTP_HOST} ^([0-9a-z-]+).domain.com [NC]
RewriteRule ^/(.*) http://domain.local/%1/$1 [P]
