Hello,
Could anybody explain me how does work caching in external helper mechanism?
I use suiqd3 (3.1.6) on debian.
I've wrote simple helper - it make sql query to sqlide db - something like that:
helper.sh:
#!/bin/sh
while read a; do
x=`sqlite /etc/squid3/db.sql "select * from user where login=\"$a\";"`
if [ -n "$x" ] ; then
echo 'OK'
else
echo 'Err'
fi
That should be upper case 'ERR'.
And in squid.conf I have:
external_acl_type logins %LOGIN /opt/squid/helper.sh
acl logins_acl external login
And so on.
In general - it works fine. If someone is in my database - traffic is
allowed, if not - denied.
But when I make update into my database, I have to restart whole squid
to see changes. Is it possible to make it work without restarting
squid?
Configure the ttl= value for the lookup results to something less than
an hour. http://www.squid-cache.org/Doc/config/external_acl_type/
Also, you may want to look at using the squid_db_auth helper installed
with Squid. It can handle any database which perl has a DBI module for.
