Learn more about the world's best-loved Web server, with examplesof Apache's authentication and logging capabilities, and also pay a briefvisit to its unique URL re-writing module.
By default, Apache logs the IP address of each requesting client. If you'dprefer something a bit friendlier, you can have Apache log the host name ofeach client, rather than the IP address. This behaviour is controlledthrough the HostNameLookups directive - turn it on to enable name lookups.
HostnameLookups On
Be warned, however, that turning this feature on is likely to slow down theWeb server, since it will have to perform a lookup for each distinctvisitor to your Web page.
And finally, you can specify the type and severity of errors that are to belogged to the error log with the LogLevel directive. A number of errorlevels are available, ranging from "emerg" and "crit" (for severe errors)to "info" and "debug" (less-critical information).
This directive comes in particularly handy when you roll your own Apacheserver and things aren't working quite as advertised.
