Description

I tried run query:
/ftp/Library/SomeLibrary/other/file.txt
or any other query:
/ftp/Library/SomeLibrary/*

I want to work location /ftp/Library/SomeLibrary, but this location silly ignore. And selected default location "".
But for page 404 this location is tested. Why?

I am use FileMon and enable debug log:

There is a problem with building location search tree under case-insensitive systems if mixed-case strings are used in location directives. As a workaround, try spelling all locations in lowercase.

Thanks for the advice. In the lower register of all works, though it is very inconvenient.

Summary: Location ignorelocation search tree incorrect on case-insensitive systems

comment:4 by Maxim Dounin <mdounin@…>, 7 years ago

In fbaae7d1c0330daf3c9259b6308bc1a58ea99ed8/nginx:

Caseless location tree construction (ticket #90).

Location tree was always constructed using case-sensitive comparison, even
on case-insensitive systems. This resulted in incorrect operation if
uppercase letters were used in location directives. Notably, the
following config:

location /a { ... }
location /B { ... }

failed to properly map requests to "/B" into "location /B".
