I think that trying to reverse-proxy an application at a different part
of the url tree to where the app thinks it is installed, is difficult.

So if application1 believes that it is installed at /app/application1,
I would suggest to expose that to the world. (Or: if you want the world
to see it at /, then configure the internal server so that it is at /
there too.)

Then your external config is mostly just "proxy_pass
http://10.1.1.10:80;", possibly with "location = / { return 301
/application/app1/; }"

The *internal* config could probably have one server{} for each
application as well.

I'm not sure why that extra section is necessary, unless the "..." part
of your config is important.
