.htaccess Snippets Awesome

A collection of useful .htaccess snippets, all in one place.

NOTE: .htaccess files are for people that do not have rights to edit the main server configuration file. They are intrinsically slower and more complicated than using the main config. Please see the howto in the httpd documentation for further details.

Disclaimer: While dropping the snippet into an .htaccess file is most of the time sufficient, there are cases when certain modifications might be required. Use at your own risk.

IMPORTANT: Apache 2.4 introduces a few breaking changes, most notably in access control configuration. For more information, check the upgrading document as well as this issue.

Credits

What we are doing here is mostly collecting useful snippets from all over the interwebs (for example, a good chunk is from Apache Server Configs) into one place. While we’ve been trying to credit where due, things might be missing. If you believe anything here is your work and credits should be given, let us know, or just send a PR.

Table of Contents

Rewrite and Redirection

Note: It is assumed that you have mod_rewrite installed and enabled.

Force www

  1. RewriteEngine on
  2. RewriteCond %{HTTP_HOST} ^example\.com [NC]
  3. RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]

Force www in a Generic Way

  1. RewriteCond %{HTTP_HOST} !^$
  2. RewriteCond %{HTTP_HOST} !^www\. [NC]
  3. RewriteCond %{HTTPS}s ^on(s)|
  4. RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

This works for any domain. Source

Force non-www

It’s still open for debate whether www or non-www is the way to go, so if you happen to be a fan of bare domains, here you go:

  1. RewriteEngine on
  2. RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
  3. RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

Force non-www in a Generic Way

  1. RewriteEngine on
  2. RewriteCond %{HTTP_HOST} ^www\.
  3. RewriteCond %{HTTPS}s ^on(s)|off
  4. RewriteCond http%1://%{HTTP_HOST} ^(https?://)(www\.)?(.+)$
  5. RewriteRule ^ %1%3%{REQUEST_URI} [R=301,L]

Force HTTPS

  1. RewriteEngine on
  2. RewriteCond %{HTTPS} !on
  3. RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
  5. # Note: It’s also recommended to enable HTTP Strict Transport Security (HSTS)
  6. # on your HTTPS website to help prevent man-in-the-middle attacks.
  7. # See https://developer.mozilla.org/en-US/docs/Web/Security/HTTP_strict_transport_security
  8. <IfModule mod_headers.c>
  9.     # Remove "includeSubDomains" if you don't want to enforce HSTS on all subdomains
  10.     Header always set Strict-Transport-Security "max-age=31536000;includeSubDomains"
  11. </IfModule>

Force HTTPS Behind a Proxy

Useful if you have a proxy in front of your server performing TLS termination.

  1. RewriteCond %{HTTP:X-Forwarded-Proto} !https
  2. RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Force Trailing Slash

  1. RewriteCond %{REQUEST_URI} /+[^\.]+$
  2. RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]

Remove Trailing Slash

This snippet will redirect paths ending in slashes to their non-slash-terminated counterparts (except for actual directories), e.g. http://www.example.com/blog/ to http://www.example.com/blog. This is important for SEO, since it’s recommended to have a canonical URL for every page.

  1. RewriteCond %{REQUEST_FILENAME} !-d
  2. RewriteCond %{REQUEST_URI} (.+)/$
  3. RewriteRule ^ %1 [R=301,L]

Source

Redirect a Single Page

  1. Redirect 301 /oldpage.html http://www.example.com/newpage.html
  2. Redirect 301 /oldpage2.html http://www.example.com/folder/

Source

Redirect Using RedirectMatch

  1. RedirectMatch 301 /subdirectory(.*) http://www.newsite.com/newfolder/$1
  2. RedirectMatch 301 ^/(.*).htm$ /$1.html
  3. RedirectMatch 301 ^/200([0-9])/([^01])(.*)$ /$2$3
  4. RedirectMatch 301 ^/category/(.*)$ /$1
  5. RedirectMatch 301 ^/(.*)/htaccesselite-ultimate-htaccess-article.html(.*) /htaccess/htaccess.html
  6. RedirectMatch 301 ^/(.*).html/1/(.*) /$1.html$2
  7. RedirectMatch 301 ^/manual/(.*)$ http://www.php.net/manual/$1
  8. RedirectMatch 301 ^/dreamweaver/(.*)$ /tools/$1
  9. RedirectMatch 301 ^/z/(.*)$ http://static.askapache.com/$1

Source

Alias a Single Directory

  1. RewriteEngine On
  2. RewriteRule ^source-directory/(.*) /target-directory/$1 [R=301,L]

Alias Paths to Script

  1. FallbackResource /index.fcgi

This example has an index.fcgi file in some directory, and any requests within that directory that fail to resolve a filename/directory will be sent to the index.fcgi script. It’s good if you want baz.foo/some/cool/path to be handled by baz.foo/index.fcgi (which also supports requests to baz.foo) while maintaining baz.foo/css/style.css and the like. Get access to the original path from the PATH_INFO environment variable, as exposed to your scripting environment.

  1. RewriteEngine On
  2. RewriteRule ^$ index.fcgi/ [QSA,L]
  3. RewriteCond %{REQUEST_FILENAME} !-f
  4. RewriteCond %{REQUEST_FILENAME} !-d
  5. RewriteRule ^(.*)$ index.fcgi/$1 [QSA,L]

This is a less efficient version of the FallbackResource directive (because using mod_rewrite is more complex than just handling the FallbackResource directive), but it’s also more flexible.

Redirect an Entire Site

  1. Redirect 301 / http://newsite.com/

This way does it with links intact. That is www.oldsite.com/some/crazy/link.html will become www.newsite.com/some/crazy/link.html. This is extremely helpful when you are just “moving” a site to a new domain. Source

Alias “Clean” URLs

This snippet lets you use “clean” URLs — those without a PHP extension, e.g. example.com/users instead of example.com/users.php.

  1. RewriteEngine On
  2. RewriteCond %{SCRIPT_FILENAME} !-d
  3. RewriteRule ^([^.]+)$ $1.php [NC,L]

Source

Exclude URL from Redirection

This snippet allows you to exclude a URL from redirection. For example, if you have redirection rules setup but want to exclude robots.txt so search engines can access that URL as expected.

  1. RewriteEngine On
  2. RewriteRule ^robots.txt - [L]

Security

Deny All Access

  1. ## Apache 2.2
  2. Deny from all
  4. ## Apache 2.4
  5. # Require all denied

But wait, this will lock you out from your content as well! Thus introducing…

Deny All Access Except Yours

  1. ## Apache 2.2
  2. Order deny,allow
  3. Deny from all
  4. Allow from xxx.xxx.xxx.xxx
  6. ## Apache 2.4
  7. # Require all denied
  8. # Require ip xxx.xxx.xxx.xxx

xxx.xxx.xxx.xxx is your IP. If you replace the last three digits with 0/12 for example, this will specify a range of IPs within the same network, thus saving you the trouble to list all allowed IPs separately. Source

Now of course there’s a reversed version:

Allow All Access Except Spammers’

  1. ## Apache 2.2
  2. Order deny,allow
  3. Deny from xxx.xxx.xxx.xxx
  4. Deny from xxx.xxx.xxx.xxy
  6. ## Apache 2.4
  7. # Require all granted
  8. # Require not ip xxx.xxx.xxx.xxx
  9. # Require not ip xxx.xxx.xxx.xxy

Deny Access to Hidden Files and Directories

Hidden files and directories (those whose names start with a dot .) should most, if not all, of the time be secured. For example: .htaccess, .htpasswd, .git, .hg…

  1. RewriteCond %{SCRIPT_FILENAME} -d [OR]
  2. RewriteCond %{SCRIPT_FILENAME} -f
  3. RewriteRule "(^|/)\." - [F]

Alternatively, you can just raise a “Not Found” error, giving the attacker no clue:

  1. RedirectMatch 404 /\..*$

Deny Access to Backup and Source Files

These files may be left by some text/HTML editors (like Vi/Vim) and pose a great security danger if exposed to public.

  1. <FilesMatch "(\.(bak|config|dist|fla|inc|ini|log|psd|sh|sql|swp)|~)$">
  2.     ## Apache 2.2
  3.     Order allow,deny
  4.     Deny from all
  5.     Satisfy All
  7.     ## Apache 2.4
  8.     # Require all denied
  9. </FilesMatch>

Source

Disable Directory Browsing

  1. Options All -Indexes

Disable Image Hotlinking

  1. RewriteEngine on
  2. # Remove the following line if you want to block blank referrer too
  3. RewriteCond %{HTTP_REFERER} !^$
  5. RewriteCond %{HTTP_REFERER} !^https?://(.+\.)?example.com [NC]
  6. RewriteRule \.(jpe?g|png|gif|bmp)$ - [NC,F,L]
  8. # If you want to display a “blocked” banner in place of the hotlinked image,
  9. # replace the above rule with:
  10. # RewriteRule \.(jpe?g|png|gif|bmp) http://example.com/blocked.png [R,L]

Disable Image Hotlinking for Specific Domains

Sometimes you want to disable image hotlinking from some bad guys only.

  1. RewriteEngine on
  2. RewriteCond %{HTTP_REFERER} ^https?://(.+\.)?badsite\.com [NC,OR]
  3. RewriteCond %{HTTP_REFERER} ^https?://(.+\.)?badsite2\.com [NC,OR]
  4. RewriteRule \.(jpe?g|png|gif|bmp)$ - [NC,F,L]
  6. # If you want to display a “blocked” banner in place of the hotlinked image,
  7. # replace the above rule with:
  8. # RewriteRule \.(jpe?g|png|gif|bmp) http://example.com/blocked.png [R,L]

Password Protect a Directory

First you need to create a .htpasswd file somewhere in the system:

  1. htpasswd -c /home/fellowship/.htpasswd boromir

Then you can use it for authentication:

  1. AuthType Basic
  2. AuthName "One does not simply"
  3. AuthUserFile /home/fellowship/.htpasswd
  4. Require valid-user

Password Protect a File or Several Files

  1. AuthName "One still does not simply"
  2. AuthType Basic
  3. AuthUserFile /home/fellowship/.htpasswd
  5. <Files "one-ring.o">
  6. Require valid-user
  7. </Files>
  9. <FilesMatch ^((one|two|three)-rings?\.o)$>
  10. Require valid-user
  11. </FilesMatch>

Block Visitors by Referrer

This denies access for all users who are coming from (referred by) a specific domain.
Source

  1. RewriteEngine on
  2. # Options +FollowSymlinks
  3. RewriteCond %{HTTP_REFERER} somedomain\.com [NC,OR]
  4. RewriteCond %{HTTP_REFERER} anotherdomain\.com
  5. RewriteRule .* - [F]

Prevent Framing the Site

This prevents the website to be framed (i.e. put into an iframe tag), when still allows framing for a specific URI.

  1. SetEnvIf Request_URI "/starry-night" allow_framing=true
  2. Header set X-Frame-Options SAMEORIGIN env=!allow_framing

  13.     # (for Apache versions below 2.3.7, you don't need to enable `mod_filter`
  14.     #  and can remove the `<IfModule mod_filter.c>` and `</IfModule>` lines
  15.     #  as `AddOutputFilterByType` is still in the core directives).
  16.     <IfModule mod_filter.c>

Set Expires Headers

Expires headers tell the browser whether they should request a specific file from the server or just grab it from the cache. It is advisable to set static content’s expires headers to something far in the future.

If you don’t control versioning with filename-based cache busting, consider lowering the cache time for resources like CSS and JS to something like 1 week. Source

  1. <IfModule mod_expires.c>
  2.     ExpiresActive on
  3.     ExpiresDefault                                      "access plus 1 month"
  5.   # CSS
  6.     ExpiresByType text/css                              "access plus 1 year"
  8.   # Data interchange
  9.     ExpiresByType application/json                      "access plus 0 seconds"
  10.     ExpiresByType application/xml                       "access plus 0 seconds"
  11.     ExpiresByType text/xml                              "access plus 0 seconds"
  13.   # Favicon (cannot be renamed!)
  14.     ExpiresByType image/x-icon                          "access plus 1 week"
  16.   # HTML components (HTCs)
  17.     ExpiresByType text/x-component                      "access plus 1 month"
  19.   # HTML

  47.     ExpiresByType font/opentype                         "access plus 1 month"
  48.     ExpiresByType image/svg+xml                         "access plus 1 month"
  49. </IfModule>

Turn eTags Off

By removing the ETag header, you disable caches and browsers from being able to validate files, so they are forced to rely on your Cache-Control and Expires header. Source

  1. <IfModule mod_headers.c>
  2.     Header unset ETag
  3. </IfModule>
  4. FileETag None

Miscellaneous

Set PHP Variables

  1. php_value <key> <val>
  3. # For example:
  4. php_value upload_max_filesize 50M
  5. php_value max_execution_time 240

Custom Error Pages

  1. ErrorDocument 500 "Houston, we have a problem."
  2. ErrorDocument 401 http://error.example.com/mordor.html
  3. ErrorDocument 404 /errors/halflife3.html

Force Downloading

Sometimes you want to force the browser to download some content instead of displaying it.

  1. <Files *.md>
  2.     ForceType application/octet-stream
  3.     Header set Content-Disposition attachment
  4. </Files>

Now there is a yang to this yin:

Prevent Downloading

Sometimes you want to force the browser to display some content instead of downloading it.

  1. <FilesMatch "\.(tex|log|aux)$">
  2.     Header set Content-Type text/plain
  3. </FilesMatch>

Allow Cross-Domain Fonts

CDN-served webfonts might not work in Firefox or IE due to CORS. This snippet solves the problem.

  1. <IfModule mod_headers.c>
  2.     <FilesMatch "\.(eot|otf|ttc|ttf|woff|woff2)$">
  3.         Header set Access-Control-Allow-Origin "*"
  4.     </FilesMatch>
  5. </IfModule>

Source

Auto UTF-8 Encode

Your text content should always be UTF-8 encoded, no?

  1. # Use UTF-8 encoding for anything served text/plain or text/html
  2. AddDefaultCharset utf-8
  4. # Force UTF-8 for a number of file formats
  5. AddCharset utf-8 .atom .css .js .json .rss .vtt .xml

Source

Switch to Another PHP Version

If you’re on a shared host, chances are there are more than one version of PHP installed, and sometimes you want a specific version for your website. The following snippet should switch the PHP version for you.

  1. AddHandler application/x-httpd-php56 .php
  3. # Alternatively, you can use AddType
  4. AddType application/x-httpd-php56 .php

Disable Internet Explorer Compatibility View

Compatibility View in IE may affect how some websites are displayed. The following snippet should force IE to use the Edge Rendering Engine and disable the Compatibility View.

  1. <IfModule mod_headers.c>
  2.     BrowserMatch MSIE is-msie
  3.     Header set X-UA-Compatible IE=edge env=is-msie
  4. </IfModule>

Serve WebP Images

If WebP images are supported and an image with a .webp extension and the same name is found at the same place as the jpg/png image that is going to be served, then the WebP image is served instead.

  1. RewriteEngine On
  2. RewriteCond %{HTTP_ACCEPT} image/webp
  3. RewriteCond %{DOCUMENT_ROOT}/$1.webp -f
  4. RewriteRule (.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]
