However, it appears that, when the screen goes blank (ie, when I'm expecting my login page to appear), it's actually crashing Squid. I've revised my helper script slightly (the STDIN apparently has a newline which confused the script): 1:#!/usr/bin/perl 2:$| = 1; 3:$ip=<STDIN>; 4:$ip=chomp($ip); 5:$ipfile='/var/www/apache2-default/cgi-bin/ips/'.$ip; 6:#print $ipfile; 7:if (-e $ipfile){print "OK";} 8:else {print "ERR : ".$ip;} This appears in the cache.log: 2008/03/05 11:33:44| WARNING: ipauth #1 (FD 7) exited 2008/03/05 11:33:44| WARNING: ipauth #2 (FD 8) exited 2008/03/05 11:33:44| WARNING: ipauth #3 (FD 9) exited 2008/03/05 11:33:44| Too few ipauth processes are running 2008/03/05 11:33:44| storeDirWriteCleanLogs: Starting... 2008/03/05 11:33:44| Finished.

Squid Cache (Version 2.6.STABLE18): Terminated abnormally. Squid then seems to restart without a problem. (Which is why I thought the redirection behaviour was to blame.) Damned if I can see what is going wrong.... Thanks again for your assistance.
