如何将所有JS，CSS，IMG重写为静态子域？

Question

I have:

sub.domain.com/js/test.js
sub.domain.com/image1.jpg
sub.domain.com/test.css

How rewrite all the file types to:

static-sub.domain.com/....

?

Thanks a lot.

Something akin to what's below should work.

RewriteEngine on
RewriteRule ^sub\.domain\.com/(js/*\.js)$ static-sub.domain.com/$1 [NC,R,L]
RewriteRule ^sub\.domain\.com/(*\.jpg)$ static-sub.domain.com/$1 [NC,R,L]
RewriteRule ^sub\.domain\.com/(*\.css)$ static-sub.domain.com/$1 [NC,R,L]

You'll likely need to tweak it to your specific scenario. Notice the usage of capturing groups ( (js/*\\.js) ) to store the variable path information to be used in the destination ( $1 ). Also note the NC , R and L options; which stand for "no casing" (case insensetive), "redirect" (redirect the request) and "last rule" (stop processing further rules if this rule is a match).
