Hi there,

This is my nginx config

```
location /app1/ {
proxy_pass http://app1/

sub_filter 'action="/' 'action="/liff/';
sub_filter 'href="/' 'href="/liff/';
sub_filter 'src="/' 'src="/liff/';
sub_filter_once off;
}
```

My problem is only index.html replacing the url but I need to replace for all files under current directory and sub directory such as assest folder.
My goal is fixing the path affter proxy_pass under localtion correctly.

Anyone got the idea, please give me a suggestion to solve this.
