 * ''password'' - optional password for basic authentication
 * ''host'' - optional hostname to serve from (defaults to "127.0.0.1" aka "localhost")
 * ''pathprefix'' - optional prefix for paths
+* ''debuglevel'' - optional debug level; set to "debug" to view request details (defaults to "none")
 
 If the password parameter is specified then the browser will prompt the user for the username and password. Note that the password is transmitted in plain text so this implementation isn't suitable for general use.
