===== Howtos =====

== 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>

== 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://wiki.digitaltrike.com/$1</code>

== Allow access from subnet only ==

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

== List modules ==

CentOS:

<code>
apachectl -t -D DUMP_MODULES
</code>

== Disable any caching on 192.168.12. subnet ==

<code>
SetEnvIf Remote_Addr 192\.168\.12\. local
<IfModule mod_headers.c>
Header set Pragma "" env=local
Header set Cache-Control "" env=local
Header set Expires "Sat, 01 Jan 2000 00:00:00 GMT" env=local
</IfModule>
</code>

== Enable PHP overrides in .htaccess ==

If PHP is installed as a CGI binary, this will not work.  But it is safe to set because of ''IfModule''.

<code>
<IfModule mod_php5.c>
php_value include_path ".:/usr/local/lib/php"
</IfModule>
</code>
