Well, if you are using mod_perl, you could install a handler for just about any stage in a request. See the mod_perl guide

On the other hand, if you just want to be notified when the access log is updated, you might try something like:

open LOG,"</var/log/httpd/access_log" or die "Cannot open log file: $! +"; seek LOG,0,2; # set to eof while (1) { while (<LOG>) { print; # or do something else... } sleep 1; # this is 1 seconds, so not exactly realtime seek(LOG, 0, 1); # reset eof flag }
