When Perl pulls a file via
require, it stores the filename in the
%INC. The next time Perl tries to
require the same
file, it sees the file in
%INC and does not reload from disk. This
module's handler iterates over
%INC and reloads the file if it has
changed on disk.
Note that StatINC operates on the current context of
Which means, when called as a Perl*Handler it will not see
added or removed by Apache::Registry scripts, as the value of
saved on server startup and restored to that value after each request.
In other words, if you want StatINC to work with modules that live in custom
@INC paths, you should modify
@INC when the server is started.

variable in the httpd's environment to include any non-standard 'lib'
directories that you choose. For example, you might use a
script called 'start_httpd' to start apache, and include a line like this:

When you have problems with modules not being reloaded, please refer to the following lines in perlmodlib:
