Most sites don't use syslog for apache access logs due to the latency
and load it introduces. Logging to a file uses much less overhead. For
a personal site or low volume company site it might not matter (only a
couple requests a second or less) but for a busy site it's a no-no.<br>

If you want network transmission something like mod_log_spread might fit the bill, but I've never used it.<br>

I looked at using it when I worked for a search engine, but some tried
and true periodic scp scripts were so trustworthy and simple that we
never replaced them.<br>
