Correct. Although you may want to add '30' as the 8th field -- that mean= s 'send signal 30 (SIGUSR1) to apache instead of SIGHUP' -- SIGUSR1 causes apache to do a graceful restart rather than abruptly killing and restarti= ng everything: http://httpd.apache.org/docs/2.2/stopping.html You'll need to experiment though -- if your user HTTP connections are=20 long-lived, you can end up with apache appending data to a rotated logfil= e that it still has an open file descriptor on. The file will be unlinked once the gzip compression has run. Now, writing to an unlinked file is allowed under Unix, but once that apache child process terminates and=20 releases the descriptor the data will disappear into the ether, so you can lose log entries.
