That is probably best done with an "if" and a "return 503" -- there are a
few approaches you can take, with their own advantages and disadvantages.

You could use "error_page" for 404 here, following
http://ngnix.org/r/error_page.

But I'll suggest using try_files with a named location as fallback.

Either way, you'll probably want one prefix and one named location,
per set of urls.

Something like:

location ^~ / {
try_files $uri $uri/ @proxyslash;
}
location @proxyslash {
proxy_pass http://127.0.0.1:8080;
}
location ^~ /testapp1/ {
try_files $uri $uri/ @proxytestapp1;
}
location @proxytestapp1 {
proxy_pass http://127.0.0.1:8081;
}
