Correct.

You will want a location{} to handle the "api" requests; and in that
location, do not have the inherited "error_page 500" directive take effect.

I think that you cannot "undo" an error_page directive from a previous
level, but you can set a "dummy" error_page directive which will have
the effect of overriding any values set at a previous level. So --
pick a http response code that you do not care about (e.g. 555) and set
error_page for that in this location.


>From your config, it looks like there are three forms of "non-api"
requests that matter:

* /one/file.html - which will return the local file
/var/www/html/gsmamarketplace/web/one/file.html

* /two/file.php - which will ask drupal to use the local file
/var/www/html/gsmamarketplace/web/two/file.php

* /three/not-a-file - which will ask drupal to use the local file
/var/www/html/gsmamarketplace/web/index.php


What forms of "api" request do you expect to receive? And what,
specifically, do you want nginx to do with each form?

That is -- do you expect "/apis/one/file.html", or "/apis/two/file.php",
or "/apis/three/not-a-file", or some of each, or something else?

When the request is for "/apis/unique_id", what file on the filesystem
do you want nginx to serve; or what file on the filesystem do you want
nginx to ask drupal to use?

Cheers,
