A modern htaccess

# ------------------------------------------------------------------------------
# Common PHP Overrides
#
# Sometimes editing your php.ini file is impossible or even just annoying.
# Here are some of the most common settings that can (sometimes) be overridden.
# ------------------------------------------------------------------------------

# php_value memory_limit 256M
# php_value post_max_size 16M
# php_value max_execution_time 90
# php_value max_input_time 120
# php_value upload_max_filesize 16M

# ------------------------------------------------------------------------------
# Base Apache Rules
#
# When running in a subdirectory, you should uncomment and adjust the
# RewriteBase rule to point to your directory, eg. RewriteBase /directory/
# ------------------------------------------------------------------------------

Options -MultiViews
RewriteEngine On
# RewriteBase /


# ------------------------------------------------------------------------------
# Remove Trailing Slashes
# ------------------------------------------------------------------------------

# RewriteCond %{REQUEST_FILENAME} !-d
# RewriteRule ^(.*)/$ /$1 [L,R=301]


# ----------------------------------------------------------------------
# Force `https://`
#
# Redirect from the `http://` to the `https://` version of the URL.
# https://wiki.apache.org/httpd/RewriteHTTPToHTTPS
# ----------------------------------------------------------------------

# <IfModule mod_rewrite.c>
#    RewriteEngine On
#    RewriteCond %{HTTPS} !=on
#    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
# </IfModule>

# ----------------------------------------------------------------------
# Suppressing / Forcing the `www.` at the beginning of URLs
# ----------------------------------------------------------------------

# The same content should never be available under two different
# URLs, especially not with and without `www.` at the beginning.
# This can cause SEO problems (duplicate content), and therefore,
# you should choose one of the alternatives and redirect the other
# one.
#
# By default `Option 1` (no `www.`) is activated.
# https://web.archive.org/web/20161122074017/http://no-www.org/faq.php?q=class_b
#
# If you would prefer to use `Option 2`, just comment out all the
# lines from `Option 1` and uncomment the ones from `Option 2`.
#
# (!) NEVER USE BOTH RULES AT THE SAME TIME!

# (1) The two rules assume by default that both HTTP and HTTPS
#     environments are available for redirection.
#     If your SSL certificate could not handle one of the domains
#     used during redirection, you should turn the condition on.
