I also have to place my zlib compression statements into a php.ini file, as well as my statement to keep TransIDs from appearing in the headers. I will show my php.ini file below the htaccess file.
Also keep in mind, this htaccess file is in the root, and so is my cart installation.
Code:
<Files .htaccess>
order allow,deny
deny from all
</Files>
DirectoryIndex index.html index.php
Options +FollowSymLinks
RewriteEngine On
# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root xcart folder (i.e. RewriteBase /shop)
RewriteBase /
# Enable the following 3 lines if you want to make sure
# all users use the www. version of your domain.
# Helps prevent cookie issues for some X-Cart installations
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^my domain name.com [NC]
RewriteRule ^(.*)$ http://www.mydomain name.com/$1 [R=301,L]
