.htaccess directory to subdomain

Question

I have been trying to make a subdomain from a directory (made by .htaccess) to be used as the main page starting like http://domain.com/sub/2/3/4.html and turning into http://sub.domain.com/2/3/4.html.

The folder system goes like:

www\sub\2\3\

in www there is a index.html and in the sub folder there is a different index.html.

I currently have this code which I found on another site:

Options -Indexes +FollowSymLinks

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]

RedirectMatch 301 ^/sub/(.*)$ http://sub.domain.com/$1

It is successful with changing the domain path to http://sub.domain.com/, but it is not successful in changing the page shown from the index in the www directory to the index in the sub directory.

It is also not successful in allowing to open other pages, i.e. not allowing sub.domain.com/2/3/4.html. If anyone can give any advice it would be much appreciated.

Solution

I have found some fantastic code for the .htaccess that converts any folder in the main www directory into sub-domains e.g. www/somefolder turns into somefolder.domain.com you can also set it so that any directory inside a certain directory becomes a subdomain e.g. www/folder/somefolder turns into somefolder.domain.com

the code below is set to redirect directory's inside a specific directory

Options +FollowSymLinks -Multiviews
RewriteEngine on
RewriteBase /
#
# Canonicalize the hostname
RewriteCond www.%{HTTP_HOST} ^(www)\.(example\.com) [OR]
RewriteCond %{HTTP_HOST} ^www\.([^.]+)\.(example\.com) [OR]
RewriteCond %{HTTP_HOST} ^([^.]+)\.www\.(example\.com) [OR]
RewriteCond %{HTTP_HOST} ^([^.]+)\.(example\.com). [OR]
RewriteCond %{HTTP_HOST} ^([^.]+)\.(example\.com):[0-9]+
RewriteRule (.*) http://%1.%2/$1 [R=301,L]
#
# If subdomain is NOT www
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
# Extract (required) subdomain to %1
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
# Rewrite if requested URL resolves to existing file or subdirectory in /subdomains/<subdomain>/ path
RewriteCond %{DOCUMENT_ROOT}/subdomains/%1/$1 -f [OR]
RewriteCond %{DOCUMENT_ROOT}/subdomains/%1/$1 -d
RewriteRule (.*) /subdomains/%1/$1 [L]

simply change 'example.com' to your domain e.g. 'domain.com' make sure you don't remove any of the other symbols apart from dots . currently the directory's in the folder called 'subdomains' will change into a subdomain e.g. www/subdomains/blog will turn into 'blog.domain.com' to set it to just change the folders in the www directory to subdomains e.g. www/blog will turn into 'blog.domain.com'

if you want to automatically forward to a subdomain e.g. blog.domain.com you will need to put this at the end of the other code

RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://blog.example.com/$1 [R=301,L]

hope this works for everyone it took me ages to find a solution to this horrible problem thanks Reblerebel

[Admin]

how would you do that?

httpd.apache.org/docs/2.0/vhosts/examples.html

[Admin]

so do i put that in the .htaccess file because i am unable to edit any other preferences

[Yun Huang]

No, this is not a .htaccess configuration. You need to edit apache's apache2.conf or httpd.conf. You'll have to ask your admin to do it then.

i am currently using free hosing which i can FTP into so would it go into the www directory?

[Yun Huang]

Then your option is to create another free hosting account for the subdomain and put your files there. This is way off-topic for stackoverflow.

[Admin]

sorry but i am unable to create a subdomain that is the whole problem
