# Non-www to www Redirect
# This is a very common function for redirecting your site 
# at the top level. Sometimes a site can be accessed at 
# http://domain.com/ and http://www.domain.com/ which can 
# cause duplication and site management issues.
#-----------------------------------------
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

# Clean up URLs to remove file extensions
# If you wanted to make your URLs look a little nicer by
# removing the file extension from the end of it you can
# use the function below. In order for this to work 
# internally to the site you should also ensure that all
# the linking within the site has the extension manually 
# removed.
#-----------------------------------------
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.*)$ $1.html

# Restrict access
# To add an element of security to the .htaccess file you
# should add the following function. It will deny access
# to anyone attempting to get to the file externally to 
# view or change it. For example, if you were to add this
# to your file and then attempt to access it at 
# http://www.domain.com/.htaccess you will be presented 
# with a 403 forbidden error. This means its working!
