WSGICaseSensitivity
===================

:Description: Define whether file system is case sensitive.
:Syntax: ``WSGICaseSensitivity On|Off``
:Default: Platform-dependent (Off on Windows and macOS, On elsewhere)
:Context: server config

When mod_wsgi is used on the Windows and macOS platforms, it will assume
that the filesystem in use is case insensitive. This is necessary to ensure
that the module caching system works correctly and only one module is
retained in memory where paths with different case are used to identify the
same script file. On other platforms it will always be assumed that a case
sensitive file system is used.

The WSGICaseSensitivity directive can be used explicitly to specify for a
particular WSGI application whether the file system the script file is
stored in is case sensitive or not, thus overriding the default for any
platform. A value of ``On`` indicates that the filesystem is case
sensitive::

Because the directive is set in the main server config, it applies to the
whole site, so every path served by Apache must reside on a filesystem
that follows the same case convention.
