正确构建具有多个规则/条件的htaccess

我如何正确地构造这个htaccess文件,以便正确地按顺序运行并避免无限循环?

RewriteEngine on 
RewriteCond %{HTTP_HOST} !^www.domain.com$
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301]
RewriteBase /
RewriteRule ^deviceToken/$ devicetoken.php [QSA,L]
RewriteRule ^register/$ register.php [QSA,L]
RewriteRule ^resetPassword/$ resetpassword.php [QSA,L]
RewriteRule ^deleteLink/$ deletelink.php [QSA,L]
RewriteRule ^getLinks/$ getlinks.php [QSA,L]
RewriteCond %{REQUEST_URI} !(\.gif)|(\.jpg)|(\.png)|(\.css)|(\.js)|(\.php)|(\.swf)|(\.xpi)|(\.ico)|(\.src)$ 
RewriteCond %{REQUEST_URI} ^(.*)$
RewriteRule (.*)$ get.php?code=$1 [L]
