Add 404 status for MS 365 autodiscover requests and omit log entries

[tormi]

Sth like this:

nginx:
  extra_conditions: |
    # 404 status for MS 365 autodiscover requests and omit log entries
    location ~ /autodiscover/autodiscover.xml {
      return 404;
      access_log off;
      log_not_found off;
    }

Saimons Jēgers:

Actually in Artis copied text both use cases say that it’s used for case-insensitive scenarios which doesn’t look right. It’s a typo on that blog/site. Link to it And this is just above the text:

~: The tilde sign is used for case-sensitive regular expression match against a requested URI.
~*: The tilde followed by asterisk sign is used for case insensitive regular expression match against a requested URI.

So it should be ~* after all.

This should be the correct one:

  locationExtraConfig: |
    # Add 404 status for autodiscover.xml requests and omit log entries.
    location ~* /autodiscover/autodiscover.xml {
      return 404;
      access_log off;
      log_not_found off;
    }
