Hosting a game is built into the game. You already have that.
The webserver interface isnt actually built in but a lot of features are that are specifically meant to enhance that.
A) being built on a PbEM format (play by email) makes it very webserver friendly for hosting.
B) the game can host in a "text mode" with pages of switches
C) there are a preexec and postexec switch which can call other programs just before hosting and just after hosting. Great for making backups or moving files into the web directory.
D) the file can output helpful files such as a scores.html and a game log.
If you are considering a linux webserver then here is a conversation on it. It would probably be helpful even if it were a windows or mac webserver. You might want to jump to the end since the simplest versions came last.
