这里收集的是各类实用的 .htaccess 代码片断,你能想到的用法几乎全在这里。javascript
免责声明: 虽然将这些代码片断直接拷贝到你的 .htaccess 文件里,绝大多数状况下都是好用的,但也有极个别状况须要你修改某些地方才行。风险自负。php
重要提示: Apache 2.4 有不兼容的修改,特别是在访问配置控制方面。详细信息请参考这篇更新文档以及这篇文章。css
注意:首先须要服务器安装和启用mod_rewrite模块。html
RewriteEngine on RewriteCond %{HTTP_HOST} ^example\.com [NC] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]
RewriteCond %{HTTP_HOST} !^$ RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteCond %{HTTPS}s ^on(s)| RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
这种方法能够使用在任何网站中。 Sourcejava
到底是WWW好,仍是non-www好,没有定论,若是你喜欢不带www的,能够使用下面的脚本:laravel
RewriteEngine on RewriteCond %{HTTP_HOST} ^www\.example\.com [NC] RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]
RewriteEngine on RewriteCond %{HTTP_HOST} ^www\. RewriteCond %{HTTPS}s ^on(s)|off RewriteCond http%1://%{HTTP_HOST} ^(https?://)(www\.)?(.+)$ RewriteRule ^ %1%3%{REQUEST_URI} [R=301,L]
RewriteEngine on RewriteCond %{HTTPS} !on RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} # Note: It's also recommended to enable HTTP Strict Transport Security (HSTS) # on your HTTPS website to help prevent man-in-the-middle attacks. # See https://developer.mozilla.org/en-US/docs/Web/Security/HTTP_strict_transport_security <IfModule mod_headers.c> Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains" </IfModule>
若是你使用了代理,这种方法对你颇有用。git
RewriteCond %{HTTP:X-Forwarded-Proto} !https RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
RewriteCond %{REQUEST_URI} /+[^\.]+$
RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [R=301,L]
Redirect 301 /oldpage.html http://www.example.com/newpage.html Redirect 301 /oldpage2.html http://www.example.com/folder/

RewriteRule ^source-directory/(.*) target-directory/$1
This example has an index.fcgi file in some directory, and any requests within that directory that fail to resolve a filename/directory will be sent to the index.fcgi script. It’s good if you want baz.foo/some/cool/path to be handled by baz.foo/index.fcgi (which also supports requests to baz.foo) while maintaining baz.foo/css/style.css and the like. Get access to the original path from the PATH_INFO environment variable, as exposed to your scripting environment.web
RewriteEngine On RewriteRule ^$ index.fcgi/ [QSA,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.fcgi/$1 [QSA,L]
This is a less efficient version of the FallbackResource directive (because using mod_rewrite is more complex than just handling the FallbackResource directive), but it’s also more flexible.sql
Redirect 301 / http://newsite.com/
This way does it with links intact. That is www.oldsite.com/some/crazy/link.html will become www.newsite.com/some/crazy/link.html. This is extremely helpful when you are just “moving” a site to a new domain. Source
This snippet lets you use “clean” URLs — those without a PHP extension, e.g. example.com/users instead of example.com/users.php.
RewriteEngine On RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^([^.]+)$ $1.php [NC,L]
## Apache 2.2 Deny from all ## Apache 2.4 # Require all denied
But wait, this will lock you out from your content as well! Thus introducing…
## Apache 2.2 Order deny,allow Deny from all Allow from xxx.xxx.xxx.xxx ## Apache 2.4 # Require all denied # Require ip xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx is your IP. If you replace the last three digits with 0/12 for example, this will specify a range of IPs within the same network, thus saving you the trouble to list all allowed IPs separately. Source
Now of course there’s a reversed version:
## Apache 2.2 Order deny,allow Allow from all Deny from xxx.xxx.xxx.xxx Deny from xxx.xxx.xxx.xxy ## Apache 2.4 # Require all granted # Require not ip xxx.xxx.xxx.xxx # Require not ip xxx.xxx.xxx.xxy
Hidden files and directories (those whose names start with a dot .) should most, if not all, of the time be secured. For example: .htaccess, .htpasswd, .git, .hg…
RewriteCond %{SCRIPT_FILENAME} -d [OR] RewriteCond %{SCRIPT_FILENAME} -f RewriteRule "(^|/)\." - [F]
Alternatively, you can just raise a Not Found error, giving the attacker dude no clue:
RedirectMatch 404 /\..*$
These files may be left by some text/html editors (like Vi/Vim) and pose a great security danger if exposed to public.
<FilesMatch "(\.(bak|config|dist|fla|inc|ini|log|psd|sh|sql|swp)|~)$"> ## Apache 2.2 Order allow,deny Deny from all Satisfy All ## Apache 2.4 # Require all denied </FilesMatch>

First you need to create a .htpasswd file somewhere in the system:
htpasswd -c /home/fellowship/.htpasswd boromir
Then you can use it for authentication:
AuthType Basic AuthName "One does not simply" AuthUserFile /home/fellowship/.htpasswd Require valid-user
This denies access for all users who are coming from (referred by) a specific domain.

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

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

CDN-served webfonts might not work in Firefox or IE due to CORS. This snippet solves the problem.
Your text content should always be UTF-8 encoded, no?
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. For example, Laravel requires PHP >= 5.4. The following snippet should switch the PHP version for you.
Compatibility View in IE may affect how some websites are displayed. The following snippet should 强制 IE to use the Edge Rendering Engine and disable the Compatibility View.
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.
