Greetings everyone,
So I'm having trouble with my squid proxy-cache server. I recently
added
a redirect program because I had to make users go to my kaspersky
admin
kit and my WSUS services to get their updates and it works fine but I
get constantly a warning and squid just collapses after a few minutes
of
run time. This is what I get in my cache.log:

FATAL: Too many queued url_rewriter requests (465 on 228)
Squid Cache (Version 2.7.STABLE7): Terminated abnormally.
This is what I have in the squid.conf
# TAG: url_rewrite_program
url_rewrite_program /etc/squid/redirect
# TAG: url_rewrite_children
url_rewrite_children 100
# TAG: url_rewrite_concurrency
url_rewrite_concurrency 50
# TAG: url_rewrite_access
url_rewrite_access allow redirect
And this is what I have in my redirector script
#!/usr/bin/perl
BEGIN {$|=1}
while (<>) {
@X = split;
$url = $X[0];
if ($url =~ /^http:\/\/dnl(.*)kaspersky(.*)com(.*)/) {
print
"301:ftp:\/\/dnl-kaspersky\.quimefa\.cu\:2122\/Updates";
}
elsif ($url =~ /^http:\/\/(.*)windowsupdate(.*)/) {
print "301:http:\/\/windowsupdate\.quimefa\.cu\:8530";
}
}
Can you please help me to solve this?
Your script does not support concurrency. When that is configured in
squid there will be 2 space-delimited fields to handle.
First one being the ID of the request channel, not the URL.
Try this:
$url = $X[1];
if ($url =~ /^http:\/\/dnl(.*)kaspersky(.*)com(.*)/) {
print $X[0]."
301:ftp:\/\/dnl-kaspersky\.quimefa\.cu\:2122\/Updates";
}
elsif ($url =~ /^http:\/\/(.*)windowsupdate(.*)/) {
print $X[0]."
301:http:\/\/windowsupdate\.quimefa\.cu\:8530";
}
