apache及nginx重写图片地址

例如需要将某个目录下的图片文件 http://m.jay520.com/uploads/1.jpg 重定向到http://rewrite.jay520.com/uploads/1.jpg

apache重写规则如下：

RewriteEngine On
RewriteRule ^uploads\/(.*)\.(gif|jpg|jpeg|png|bmp|swf)$ http://rewrite.jay520.com/uploads/$1.$2 [R,NC,L]

nginx重写规则如下：

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
     expires 30d;
     rewrite "^/uploads\/(.*)$" http://rewrite.jay520.com/uploads/$1;
}
