squid not killing my url_rewriters

[Chris Woodfield <rekoil@xxxxxxxxxxxxx>]

Hi all,

I'm working on a custom url_rewriter helper app, written in perl, that  
translates incoming URL requests to custom URLs using a config file  
that is loaded at startup and is polled for changes at regular  
intervals.

In order to handle the update polling, the script uses POE for event  
handling, using POE::Filter::Line to handle incoming URL requests from  
squid and then a delay to handle the config poll interval.

The problem I've found, which I didn't have when the first iteration  
of the script was simply a while(<>) loop, is that when squid exits or  
is HUP'ed, it kills the existing helper apps by sending an EOF (Ctrl- 
D). However, POE's signal handling doesn't seem to be able to respond  
to EOF (only KILL, HUP, etc), and as such, the children never exit.

Anyone know enough about POE to let me know if I'm missing something I  
can do in my code in order to enable POE's handling the EXIT/EOF/CRTL- 
D signal? Or a way to make squid use KILL instead of EOF to kill off  
the url rewriters for sure?

Thanks,

-Chris
