[TriLUG] split apache logfiles

[Jason Tower]

is it possible to split up the log files for a virtual host www.foo.com  
such that all requests for files in /bar of the document root get 
logged to logs/bar/combined_log while everything else gets logged to 
logs/combined_log?  it looks like conditional logging using the  
SetEnvIf parameter will allow me to mark requests, i'm just not sure 
how to direct them to the appropriate logiles.  thanks!
