multiple log files

Each Virtual Host has the options of sending logs to separate files. So, you have the choice of one combined log file vs. several individual log file.

My question is, what if you wanted both? Could you write log files to individual files but also have them write to one central file?

Simply add another CustomLog line to your VirtualHost block and specify a different log file name.
