Another "nested locations" question

Server NGINX
1

I am interested in using a nesting of some sort so that I don’t have to
duplicate all the proxy- and other directives for one “special case”.

Basically, I’d like a very small subset of my webapp to also write to a
separate access-log. When a user hits that particular page, I would
like to log it, AND also perform all the directives for the rest of the
site that are already configured.

Something like

location /site {
location /site/search {
access_log /var/log/nginx/search_access.log;
}
proxy_pass …
proxy_redirect off;
proxy_set_header …
}

So accessing /site/search should write an entry in the “special log
file”, and then do all the “normal stuff” that location /site has
itemized.

Is this possible?

Thanks again,
AJ

Not exactly. Each location is expected to have it’s own “do
something” list, i.e. if you need proxy_pass in this location -
you have to write it explicitly.

On the other hand, there is no need to duplicate normal
configuration, e.g. proxy_redirect and proxy_set_header will be
inherited from previous level(s). I.e. you have to write
explicitly only few directives which aren’t inherited, notably
try_files, rewrite module directives, and content handlers like
proxy_pass.

In the above config snippet you have to duplicate proxy_pass into
location /site/search.

OK, I am positive this is easy for you experienced nginx users!

I have a backend app server setup and am using nginx for
caching/proxy/ssl-termination.

I would like to use the “default” server (listening on 443) to redirect
the url https://host/monit to the server’s monit-mini-http server (and
continue to use it for ssl termination). so I need to direct the
backend to http://localhost:2812/.

Thus, I think I need a proxy_pass and a rewrite (to basically just
remove “/monit” from the url (pass the remainder of the url back to
monit’s http server from root). I was trying to do this inside a
location /monit { }.

But, of course, I can’t get it to work. :frowning:

Any hints?

Very basic. No rewrites.

location ^~ /monit {
location ~* ^/monit/(?<monit_request_uri>.*)$ {
proxy_pass http://127.0.0.1:2812/$monit_request_uri;
proxy_set_header Host $host;
}

Err, make that:

location ^~ /monit {
location ~* ^/monit(?<monit_request_uri>.*)$ {
proxy_pass http://127.0.0.1:2812/$monit_request_uri;
proxy_set_header Host $host;
}

This way https://myserver/monit won’t give a 404.

The regex is not required:

location ^~ /monit/ {
proxy_pass http://127.0.0.1:2812/;
proxy_set_header Host $host;
}

Requests to “/monit” will be redirected to “/monit/” automatically.

So this probably will work if I have the access_log AND include a copy
of the proxy_pass directives in the nested location. The
proxy_set_header, proxy_cache…, etc. would all be inherited
automatically in the nested location, so I can leave those in the
parent?

Feel free to add other headers to your liking.

Yes. You actually can leave those on server or even http level,
and these directives will be inherited from there as well.
