Htaccess - too many redirects

Question

Hi I have problem with my htaccess. I have new version of website (located at www.mywebsite.cz) and old version (located at mywebsite.cz (without www)).

I need to redirect all non-www pages to www except folder admin which always has to be non-www. Example:

mywebsite.cz/admin/ -> mywebsite.cz/admin/
www.mywebsite.cz/admin/ -> mywebsite.cz/admin/

I have these two htaccess files, one for new website and one for older.

Old website htaccess:

Options +FollowSymLinks 
Options -Indexes
RewriteEngine On
#RewriteBase  /

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{REQUEST_URI} !^/admin/ [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

New website htaccess:

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{REQUEST_URI} ^/admin/ [NC]
RewriteRule ^(.*)$ http://mywebsite.cz/admin/ [R=301,L]

RewriteRule /\.|^\. - [F]
# front controller
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule !\.(pdf|js|ico|gif|jpg|png|css|rar|zip|tar\.gz)$ index.php [L]

Problem is when i try www.mybsite.cz/admin/ it returns too many redirects. Can somebody help me please?

Answer 1

Add this as the first rule in your new website's htaccess:

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ - [L]

Alternatively, exclude /admin from your front controller rule as

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/admin(/.*)? [NC]
RewriteRule !\.(pdf|js|ico|gif|jpg|png|css|rar|zip|tar\.gz)$ index.php [L]
