Inform mod_perl application that the apache server has restarted

Question

What's the best way (assuming there is one) to inform a mod_perl application that the apache web-server it's running under recently restarted?

I ask because when I restart the server I'd like to clear memcached, however in that case, I need to inform the application that memcached has reset so that the application can initialise the data again.

You can put this sort of logic in a startup file. This file will be executed on Apache (re)start. In your Apache config:

 PerlPostConfigRequire /home/httpd/perl/lib/startup.pl
