squid syslog-ng, problem rotate

[Luis Enrique Sanchez Arce <lesanchez@xxxxxx>]

I have configured Squid to send the log to syslog.

I Use the following configuration:

access_log syslog squid

When squid rotate de log, stop send the log messages to syslog-ng.

In syslog-ng I have de following configuration:
A program that reads from standard input the line that squid send.

----------------------------------------------------------------------------------
source s_squid {
        # standard Linux log source (this is the default place for the syslog()
        # function to send logs to)
        unix-stream("/dev/log");
};

filter f_squid { program("squid") and match("TCP_|UDP_|ERR_");};

destination d_squid_prog {
        program("/usr/local/quota" template("$MSGONLY\n") log_fifo_size(50000));
};

log {
    source(s_squid);
    filter(f_squid);
    destination(d_squid_prog);    
};

------------------------------------------------------------------------------------

Exist another way to read from standard input the squid access_log ?

Sorry for my english.
