Is there a limitation in nginx on the number of simultaneous via proxy_pass

[glareboa]

If do index.html and nginx.conf like below, that displays all

index.html
-------------------------
<div class="d-td" id="1">
   <img src="/aaa/">
</div>
...

nginx.conf
---------------------------
location /aaa/
{
   rewrite ^/aaa/  http://mysite.org:9000";
}
...
