Need help cleaning up .htaccess

Question

I am looking at an .htaccess file in a project that I'm helping with and it appears that some of the code in it is redundant. Can it be cleaned-up a bit? Here's the code:

<Files .htaccess>
order allow,deny
deny from all
</Files>

# Add Caching
<FilesMatch "\.(png|gif|js|css)$">
  ExpiresActive on
  ExpiresDefault "access plus 1 month"
</FilesMatch>

# EXPIRES CACHING ##
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access 1 year"
    ExpiresByType image/jpeg "access 1 year"
    ExpiresByType image/gif "access 1 year"
    ExpiresByType image/png "access 1 year"
    ExpiresByType text/css "access 1 month"
    ExpiresByType text/html "access 1 month"
    ExpiresByType application/pdf "access 1 month"
    ExpiresByType text/x-javascript "access 1 month"
    ExpiresByType image/x-icon "access 1 year"
    ExpiresByType application/x-httpd-php "access plus 1 month"
    ExpiresDefault "access 1 month"
</IfModule>
# EXPIRES CACHING ##


# disable directory autoindexing
Options -Indexes

ErrorDocument 400 https://domain.name
ErrorDocument 401 https://domain.name
ErrorDocument 402 https://domain.name
ErrorDocument 403 https://domain.name
ErrorDocument 405 https://domain.name
ErrorDocument 404 /incl/pages/error404.php
ErrorDocument 500 https://domain.name

RewriteEngine On

# https
RewriteCond %{HTTPS} off

# END GZIP

# Stop hotlinking.
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://([^/]+)/ [NC]
RewriteCond %1#%{HTTP_HOST} !^(.+)#\1$
RewriteRule \.(jpg|jpeg|png|gif|swf|svg)$ - [NC,F,L]

# Compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

Answer 1

You have couple of extra rewrite rules that can be merged into a single redirect for https and www removal.

Here is the suggested full .htaccess:

<Files .htaccess>
order allow,deny
deny from all
</Files>

# Add Caching
<FilesMatch "\.(png|gif|js|css)$">
  ExpiresActive on
  ExpiresDefault "access plus 1 month"
</FilesMatch>

# EXPIRES CACHING ##
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access 1 year"
    ExpiresByType image/jpeg "access 1 year"
    ExpiresByType image/gif "access 1 year"
    ExpiresByType image/png "access 1 year"
    ExpiresByType text/css "access 1 month"
    ExpiresByType text/html "access 1 month"
    ExpiresByType application/pdf "access 1 month"
    ExpiresByType text/x-javascript "access 1 month"
    ExpiresByType image/x-icon "access 1 year"
    ExpiresByType application/x-httpd-php "access plus 1 month"
    ExpiresDefault "access 1 month"
</IfModule>
# EXPIRES CACHING ##

# disable directory autoindexing
Options -Indexes

ErrorDocument 400 https://domain.name
ErrorDocument 401 https://domain.name
ErrorDocument 402 https://domain.name
ErrorDocument 403 https://domain.name
ErrorDocument 405 https://domain.name
ErrorDocument 404 /incl/pages/error404.php
ErrorDocument 500 https://domain.name

RewriteEngine On

# remove www and turn on https in the same rule
RewriteCond %{HTTP_HOST} ^www\. [NC,OR]
RewriteCond %{HTTPS} !on
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L,NE]

# Stop hotlinking.
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://([^/]+)/ [NC]
RewriteCond %1#%{HTTP_HOST} !^(.+)#\1$
RewriteRule \.(jpe?g|png|gif|swf|svg)$ - [NC,F,L]

# BEGIN GZIP
<ifmodule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript application/x-httpd-php
