Apache 简单的mod_重写重定向

经过大量的研究和帮助，我终于了解了一点mod rewrite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/$1 [R=301,L]

######redirect naked to www
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L]

######redirect IP to www
RewriteCond %{HTTP_HOST} ^100\.100\.100\.100$
RewriteRule ^(.*)$ http://www.example.com/$1 [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/$1 [R=301,L]

谢谢

还有，这两者之间的区别是什么：

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

及

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]

根据我们之前的谈话。您还可以组合

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/$1 [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/$1 [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/$1 [L,R=301

这是另一种方式。

你面临什么问题？@anubhava:

www.example.com/image.png

不会重定向到

static.example.com/image.png

@MainHero第一条规则应该为你做到这一点。你是说它现在不工作了吗？@Panama-Jack:好像和我的浏览器有关。。。我遇到的第二个错误是无休止地重定向到static.example.com。你能解释一下

^（www\）？

的作用吗？它可以匹配

www

，也可以选择匹配

www.example.com

和

example.com

######redirect naked to www or IP
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule (.*) http://www.example.com/$1 [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/$1 [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/$1 [L,R=301
