 +RewriteCond %{HTTP_USER_AGENT} ^Mozilla/​4\.0\ \(compatible\) [OR]

 +==== How to prevent asking for download files ====
 +
 +This will not ask you to download files.
 +
 +<code apache | .htaccess>​
 +AddType application/​octet-stream .pdf
 +AddType application/​octet-stream .zip
 +AddType application/​octet-stream .mov
 +</​code>​
 +
 +==== Redirect Non-www to www domain ====
 +This is useful in may stats.
 +
 +<code apache | .htaccess>​
 +RewriteEngine On
 +RewriteCond %{HTTP_HOST} !^www\.
 +RewriteRule ^(.*)$ http://​www.%{HTTP_HOST}/​$1 [R=301,L]
 +</​code>​
 +
 +==== Redirect www to Non-www ====
 +
 +<code apache | .htaccess>​
 +RewriteEngine On
 +RewriteCond %{HTTP_HOST} ^domain.com
 +RewriteRule (.*) http://​www.domain.com/​$1 [R=301,L]
 +</​code>​
 +

 +RewriteRule (.*) http://​www.google.com/​search?​hl=en&​site=domain.com&​q=domain.com&​btnG=Search [R=301,L]
 +</​code>​
 +
 +==== flv streaming + mp4 streaming with lighttpd proxy ====
 +
 +<code apache | httpd.conf>​
 +ProxyRequests Off
 +ProxyPass /video http://​127.0.0.1:​81/​
 +ProxyPassReverse / http://​127.0.0.1:​81/​
 +</​code>​
 +
 +In light httpd simply follow the configuration as usual.

 +
 +<code apache>
 +RewriteEngine On
 +RewriteRule ^(.*)\.(mp3|mov|mp4)$ http://​www.xyz.com:​81/​Videos/​$1.$2 [NC]
 +</​code>​
 +
 +==== Redirect mobile browser ====
 +
 +This will help to redirect all mobile devices to specific page.
 +
 +<code apache>
 +RewriteEngine On
 +RewriteCond %{HTTP_USER_AGENT} (mobile|android|blackberry|brew|htc|j2me|lg|midp|mot|motorola|netfront|nokia|obigo|openweb|opera.mini|palm|psp|samsung|sanyo|sch|sonyericsson|symbian|symbos|teleca|up.browser|vodafone|wap|webos|windows.ce) [NC]
 +RewriteRule ^(.*)$ http://​ketan.lithiumfox.com/​doku.php?​do=search&​id=htaccess [R=303,L]
 +</​code>​
 +
 +Why 303 :
 +The response to the request can be found under another URI using a GET method. When received in response to a PUT,\\
 +it should be assumed that the server has received the data and the redirect should be issued with a separate GET message.
 +
 +
 +==== Disable Trace / track ====
 +
 +Mostly trace / track is risk to apache server.\\
 +
 +<code apache>
 +RewriteEngine on
 +RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
 +RewriteRule .* - [F]
 +</​code>​
