Before you install WebDoubler, make sure that your computer is properly configured. For WebDoubler, this means that your both your LAN and Internet connections are working properly, and that you have enough RAM and hard drive space.
If you have downloaded WebDoubler from the Internet, use Stuffit Expander or similar tool to extract the WebDoubler folder from the download package. If you have received WebDoubler on diskette or CD-ROM, double-click on the WebDoubler Installer icon to have the WebDoubler folder installed on your hard drive. In either case, the WebDoubler folder created will include all of the components of WebDoubler. No system extensions or other files will be placed anywhere else on the computer.
The WebDoubler folder will contain:
To run WebDoubler, double-click the WebDoubler application icon. If you would like to automatically run WebDoubler when your Macintosh starts up, place an alias of the WebDoubler application icon in the "Startup Items" folder of your System Folder.
The first time you run WebDoubler, the Statistics window will automatically open, displaying a variety of information about the activity on your server. If this window is not visible, you may at any time open it by choosing the "Statistics" item from the "Server" menu.
Basic server settings are accessed by choosing the "Configuration..." item from the Server menu. When the Configuration window opens, the "Server" tab will automatically be selected.
WebDoubler's default configuration settings are a good starting point for most WebDoubler installations. In fact, in most cases WebDoubler can be used without adjusting any of the initial configuration settings. One basic setting you should be sure to change, however, is the remote administration username and password.
However, you should also note that most modern Web browsers will initiate multiple client connections while downloading a single Web page. Usually, a single Web page access from a single Web client may result in five or more simultaneous client connections. Therefore, we recommend configuring WebDoubler to permit no less than 16 simultaneous connections.
The best way to determine the proper setting for Max. Connections is to periodically check the "Simultaneous Connections" statistic in the Peak Usage section of the main Statistics window. If the number of peak simultaneous connections is substantially lower than the configured number of maximum connections, you can most likely save RAM and CPU horsepower by reducing the number of maximum connections to a number slightly higher than the peak. If, on the other hand, the Simultaneous Connections statistic is always equal to the maximum number of connections you have configured in WebDoubler, you may need to increase the Max. Connections setting.
If you increase the Max Connections setting, you may also need to increase the amount of RAM allocated to WebDoubler. See details later in this section for how to change WebDoubler's RAM partition. For more information on optimizing the number of maximum connections for your network, see the WebDoubler page on the Maxum Web site.
Important Security Note: When you first install WebDoubler, the Browser Administration username and password will be set to their default values of "auric" and "goldfinger". We strongly recommend that you change these from the default settings. If you do not, anyone on the Internet or on your LAN will be able to use the default username and password to change the configuration settings in WebDoubler running on your server.
| Debug | Extremely detailed messages describing most low-level functions |
| Verbose | Detailed messages describing most high-level functions |
| Basic | Simple messages that note processed requests |
| Warnings | Messages are sent only when unexpected processing is required |
| Errors | Messages are sent only when errors occur |
| Suspend | No messages are sent to the error log at all |
For normal operation, we recommend that the error level be set to either "Warnings", "Errors", or "Suspend". Additional detail will be saved to the error log by selecting one of the other priorities, but will cause unnecessary disk access which may decrease server performance. If you are having a specific problem and would like to log very detailed information, setting the error level to "Verbose" or "Debug" can be extremely helpful but should not be used under normal conditions.
The messages saved in the error log file can also be displayed in real time using the Activity Monitor window. See the section "Using WebDoubler" for more information on using the Activity Monitor.
While the minimum amount of RAM that WebDoubler needs to run properly is 16 MB (16,384 K), WebDoubler performance can be significantly improved by giving it additional RAM to use for file caching and supporting more simultaneous users.
To allocate additional RAM to WebDoubler, follow these steps:
For up to date information on recommended RAM allocation based on a variety of variables (number of users, Internet connection speed, etc.) visit the WebDoubler page on Maxum's Web site.
