The TCP port on which the Web server should listen for HTTP requests.
The standard port for HTTP is 80, so if you use another port you need to
include it in the URL. For example, if you let your Web server listen
on port 8000, then the URL to your server would be
http://your.webserver.com:8000/.
The Web server stores the PID of its main process in this file. You will probably not need to modify this.
How many seconds the Web server will wait for a request to be sent after a client has connected to the server. If a client connects but doesn't send any request, it will be disconnected after this amount of time.
Whether the Web server should attempt to find out the host names of connecting clients. If this is disabled, only the IP address of the client will be logged. If you enable it, the host name will be logged instead, if it is possible to resolve the IP address to a name.
There are two disadvantages of enabling host name lookups. Every access results in network traffic to resolve the address, and the accessed page can't be returned until after the address is resolved, so your Web server will be slowed down. If you're interested in seeing the host names of machines accessing your Web server, a better idea is to let a log file analyzer resolve the addresses as it processes the log files.
