# TaskJuggler::WebServer

The WebServer class provides a self-contained HTTP server that can serve HTML versions of Report objects that are generated on the fly.

### Attributes

authKey[RW]
port[RW]
uriFile[RW]
webServerPort[RW]

### Public Class Methods

Create a web server object that runs in a separate thread.

    def initialize
      super
      # For security reasons, this will probably not change. All DRb
      # operations are limited to localhost only. The client and the sever
      # must have access to the identical file system.

      # The default TCP/IP port. ASCII code decimals for 'T' and 'J'.

      # file. Otherwise the daemon will not start.

        # When the OS sends us a TERM signal, we try to exit gracefully.
