[ljw79618@gmail.com]

I want to using proxy_cache in front of internal location,but proxy_pass not
work.my code like following:

location /proxy {
    proxy_cache cache;
    proxy_cache_key $uri;
    proxy_cache_valid 200 304 10d;
    expires 10d;
    proxy_pass @bar;
}

location @bar {
    internal;
    content_by_lua '
            ngx.log(ngx.ERR,"sssssssssssssssssss")
            ngx.say("yaha")
        ';
}

proxy_cache must used with proxy_pass?any other method to do this?

Thanks.
