Redirect for SSL

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Another SSL redirect option

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

SSL redirect SSL Proxy

RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

Another SSL Redirect for proxy

For those code troubling sites that complicate things to the extreme 

RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/?(.*)  https://www.domain.com/$1 [L,R,NE]

In the odd case they want to redirect a specific page back to http

RewriteEngine On
RewriteCond %{ENV:HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Two domains pointing at a website one has a different starting point.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.domain.com$
RewriteRule ^$ http://domain.com/filename.html [L,R=301]

301 Redirect

Redirect 301 /oldfile.htm http://example.net/

Note that while the old file is a necessary parameter, it can be set to '/' (without the single quotes) to define all requests to that folder. Such as: 

Redirect 301 / http://example.net/

Some people like to use this so it appears its only without www, you could do the reverse and have it for non www go to www 

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

Auth for Single Page or Multiple

Protect pages via htaccess or even whole directories.

This will help with creating the htpasswd file http://www.htaccesstools.com/htpasswd-generator/ 

<Files "mypage.html">
#if you want the whole directory you don't require the Files clause here
# also if you have the entirety of the auth info in the files clause you can do separate files with separate login information
AuthType Basic
AuthName "Protected Page"
AuthUserFile /Full/Path/To/.htpasswd
Require valid-user
</Files>

htaccess caching

<IfModule mod_headers.c>
# YEAR
<FilesMatch ".(ico|gif|jpg|jpeg|png|flv|pdf)$">
 Header set Cache-Control "max-age=29030400"
</FilesMatch>
# WEEK
<FilesMatch ".(js|css|swf)$">
 Header set Cache-Control "max-age=604800"
</FilesMatch>
# 24 HOURS
<FilesMatch ".(html|htm|txt|php)$">
 Header set Cache-Control "max-age=86400"
</FilesMatch>
</IfModule>

Mobile Redirect

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} iPad
RewriteCond %{REQUEST_URI} ^/$
RewriteRule .* /SRSmobile/ipad\.html [R]
RewriteCond %{HTTP_USER_AGENT} iPhone
RewriteCond %{REQUEST_URI} ^/$
RewriteRule .* /SRSmobile/iphone\.html [R]

Two Domains One Wordpress

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

Deflate for compression

# 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

301 redirect for multiple domains one hosting

RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^/?(.*)         http://www.domain.com/$1 [L,R,NE]


Redirect Subdomain to Specific URL

If you need to redirect a subdomain to a specific URL without using a directory pointer, try the code below. This example is for a blog, but any subdomain combined with any destination URL will work. 

RewriteEngine On
RewriteCond %{HTTP_HOST} ^blog\.domain\.com$ [NC]
RewriteRule ^(.*) http://domain.com/blog.html [L,R]


Rewrite Flags

At the end of a Rewrite code you can set multiple parameters in square brackets... 
[like this]
Each one is usually a single letter code or initialism. For example L stands for "Last" which makes that the last rule to process. You can find a full list and descriptions here: [1]


Case Sensitivity and Mod Spelling

Add the below code to a .htaccess file to disable case sensitivity of filenames. This also allows minor misspellings of filenames to return results.
