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

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

RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteCond %{HTTP_HOST} !^$
RewriteRule ^/?(.*) http://www.domain.com/$1 [L,R,NE]
Redirect Subdomain to Specific URL
If you need to redirect a subdomain to a specific URL without using a directory pointer, try the code below.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^new\.domain\.com$ [NC]
RewriteRule ^(.*) http://domain.com/new.html [L,R]
