Depending on the environment, seperate log files per web "site"/"domain" may make lots of sense. if each domain is a seperate customer it can be better to log to seperate files then to log to one file and then have to split it up later (touching the data an extra time)

"If users are made to understand that the system administrator's job is to make computers run, and not to make them happy, they can, in fact, be made happy most of the time. If users are allowed to believe that the system administrator's job is to make them happy, they can, in fact, never be made happy." - -Paul Evans (as quoted by Barb Dijker in "Managing Support Staff", LISA '97)
