braces and nginx rewrite rule

Question

How do I use braces in nginx rewrite rules, e.g.

rewrite ^(.*)\.[0-9]{8,}\.(js|css|png|jpg|gif|bmp) $1.$2 last;

running

nginx -t

gives an error, saying the rewrite rule is not terminated by ';', how can I fix this?

Thanks.

Answer 1

looks quoting the regex works

 rewrite "^(.*)\.[0-9]{8,}\.(js|css|png|jpg|gif|bmp)" $1.$2 last;
