Apache Reference: mod_perl, PerlFreshRestart

PerlFreshRestart

Reload of Modules and Scripts on Restarts
Syntax: PerlFreshRestart on|off
Example: PerlFreshRestart on
Since: Apache 1.2

This directive forces mod_perl to completely reload Perl modules (-> PerlModule) and scripts (-> PerlRequire) at every restart. As a result, changes to the start-up script and other Perl modules can take effect on restarts without the need to bring the server completely down. By default, the modules and scripts are cached even over server restarts. This default is mainly intended for developers.
