Directory structre change using .htaccess

Question

I want to move all my web site files (even including index.php) into a subdirectory (for exp: "abc")

For example BEFORE:

public_html
 index.php
 a.file
 directory
   an.other.file
 ...

AFTER:

public_html
 abc_directory
   index.php
   a.file
   directory
     an.other.file
   ...

I want everything to work, as it was before, but i don't want to make any redirections (visible).

People should enter "http://myexmaplesite.com/directory/an.other.file/" and by .htaccess apache serve them "http://myexmaplesite.com/abc_directory/directory/an.other.file/" BUT WITHOUT EXTERNAL REDIRECTS (301,302 etc.)

How could I route all requests to a subdirectory using mod_rewrite?

Answer 1

Something like

RewriteEngine On
RewriteBase /
RewriteRule ^(.*)$ directory/$1 [L,QSA]

Answer 2

Try this mod_rewrite rule in your document root:

RewriteEngine on
RewriteRule !^directory/ directory%{REQUEST_URI} [L]

Or in general:

RewriteEngine on
RewriteCond $1 !^directory/
RewriteRule ^/?(.*) directory/$1 [L]

This should be even applicable in server or virtual host configurations.
