简单 mod_rewrite 重定向

Question

经过大量研究和一些帮助，我设法了解了一些 mod 重写的工作原理...有人能告诉我下面的代码有什么问题吗？

######redirect all static files to the static domain
RewriteCond %{REQUEST_URI} ^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]
RewriteRule ^(.*)$ http://static.example.com/ [R=301,L]

######redirect naked to www
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule (.*) http://www.example.com/ [R=301,L]

######redirect IP to www
RewriteCond %{HTTP_HOST} ^100\.100\.100\.100$
RewriteRule ^(.*)$ http://www.example.com/ [R=301,L]

######redirect all non static files from static domain (because that remains) to www
RewriteCond %{REQUEST_FILENAME} !\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]
RewriteRule ^(.*)$ http://www.example.com/ [R=301,L]

谢谢！

另外，有什么区别：

RewriteCond %{REQUEST_URI} !^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]

和

RewriteCond %{REQUEST_FILENAME} !\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]

Answer 1

试试这个 .htaccess:

######redirect all static files to the static domain
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteRule \.(gif|png|jpe?g|jfif|bmp|css|js)$ http://static.example.com%{REQUEST_URI} [R=301,L,NC]

######redirect naked to www
RewriteCond %{HTTP_HOST} ^example\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^100\.100\.100\.100$
RewriteRule ^ http://www.example.com%{REQUEST_URI} [R=301,L]

######redirect all non static files from static domain (because that remains) to www
RewriteCond %{HTTP_HOST} ^static\. [NC]
RewriteRule !\.(gif|png|jpe?g|jfif|bmp|css|js)$ http://www.example.com%{REQUEST_URI} [R=301,L,NC]

Answer 2

基于我们之前的谈话。您还可以结合使用 www 和 IP 规则。它只需要检查 www 是否不存在。

######redirect naked to www or IP
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule (.*) http://www.example.com/ [R=301,L]

######redirect all static files to the static domain
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC] 
RewriteCond %{REQUEST_URI} ^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]
RewriteRule ^(.*)$ http://static.example.com/ [R=301,L]

######redirect all non static files from static domain (because that remains) to www
RewriteCond %{HTTP_HOST} ^images\.example\.com [NC]
RewriteCond %{REQUEST_URI} !^/(.+)\.(gif|png|jpg|jpeg|jfif|bmp|css|js)$ [NC]
RewriteRule ^(.*)$ http://www.example.com/ [L,R=301

这是另外一种方式。
