angular - nginx or apache how to serve content from /subfolder no matter what url you are at -

i have frontend app, written in angular, hosted @ http://localhost/subfolder/myapp

when go app, redirects route1, url appears as: http://localhost/subfolder/myapp/route1

but when refresh browser, 404 not found error. think that's because there no physical index.html in /subfolder/myapp/route1 , /subfolder/myapp/route1 not physical folder.

so wrote rewrite rule

rewrite ^/subfolder/myapp/.+$ /subfolder/myapp last; 

but since when go http://localhost/subfolder/myapp redirected http://localhost/subfolder/myapp/route1, , rule redirecting me http://localhost/subfolder/myapp, in infinite redirect state (too many redirect problem)

what can in nginx solve problem? or apache?

figured out:

    location /subfolder/myapp/ {         try_files $uri /subfolder/myapp/index.html;     }      location /subfolder2/myapp/ {         try_files $uri /subfolder2/myapp/index.html;     }
