3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen <p>The Status module allows a server administrator to find out
3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen how well their server is performing. A HTML page is presented
3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen that gives the current server statistics in an easily readable
3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen form. If required this page can be made to automatically
3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen refresh (given a compatible browser). Another page gives a
3b40d219e6e756e68d1b7a4dd9489f9ef7bdbabcrbowen simple machine-readable list of the current server state.</p>
