==== Redirects ====

^ Status ^ Definition ^
| 301 | Moved permanently |
| 307 | Temporary redirect |

== Redirect a single file ==

<code>
Redirect 301 /d/file.html /ddd/file.html
</code>

== Redirect entire site to new domain ==

<code>
Redirect 301 / http://www.domain.com
</code>

== Redirect site to HTTPS ==

<code>RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</code>

== Redirect all non-domain names to the domain ==

<code>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.domain.com
RewriteRule (.*) http://www.domain.com$1 [R=301,L]
</code>

Same with not specifying a specific domain -- works for virtual hosts:

<code>
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</code>

== Redirect non-www prefix for a domain to www ==

<code>
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
</code>

== Rewrite if REQUEST_URI matches string ==

You can use Perl regular expression syntax with RewriteCond

<code>RewriteEngine On
RewriteCond %{REQUEST_URI} ^/(dmc)?wiki
RewriteRule ^(.*)$ https://nx.beandog.org/$1</code>

==== Access ====

== Allow access from subnet only ==

<code>
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
</code>

== Require either user authentication or subnet access ==

The ''DirectoryMatch'' here restricts access to ''*-dev'' sites:

<code>
<DirectoryMatch "/var/www/html/(.*\-dev)/">
        Order allow,deny
        Allow from 192.168.12.0/24
        AuthType Basic
        AuthName "Development Sites"
        AuthUserFile /var/www/dev-access.htpasswd
        Require valid-user
        Satisfy any
</DirectoryMatch>
</code>
