Dynamic Subdomain Redirect.

Hi all ,

have read Nintendos excellent post on htaccess but not sure if its htaccess or php redirect im looking at.(im experimenting)

I have domain www.domain.com
I have 5 directorys inside. So www.domain.com/dir1 ( for example)
I have ( example ) 5 subdomains on a domain to match dirs ( so dir1.domain.com)
Im looking to redirect dir1.domain.com to www.domain.com/dir1 but still preserving the domain dir1.domain.com.
I know I could setup hosting to point dir1.domain.com to /public_html/dir1.

*But*
All domains point to /public_html
These arent actually directorys , they are rewritten categorys.

Any ideas

 

You can solve this with either PHP or RewriteRules.

In PHP:

<?php
  if(stristr($_SERVER['HTTP_HOST'], "dir1.domain.com"))
  {
    header("Location: http://www.domain.com/dir1", TRUE, 301);
    exit();
  }
?>

PHP:

With RewriteRules:

RewriteCond %{HTTP_HOST} dir1.domain.com [NC]
RewriteRule .* http://www.domain.com/dir1 [R=301,L]

Code (markup):

Both versions will behave exactly the same way, each doing a case-insensitive comparison of the hostname with each directory name and if it matches the directory names, respond with a 301 redirect to the correct directory on the www domain.

 

Thanks for that , green added
