General Server Options

Click the View menu and select Options.

Administrator

The Administrator option regulates the frequency at which the Administrator panels will be refreshed.

Timeout Values

The Timeout values affect the internal behavior of the Web Application Server. These are normally left untouched unless your web applications have specific and lengthy operations. Whenever a timeout occurs, the Web Application Server creates an entry in the NT Event Log. If you experience timeouts, you can change these values.

Transaction Timeout

When the server process takes more time than the number of milliseconds specified here, the process will be killed, the user will see an error, and you will find a note in the Windows Event Viewer.

Performance

Max Concurrent Sessions

The Max Concurrent Sessions option is a server-wide setting that determines the maximum number of sessions allowed to run simultaneously. If set to zero, no limit applies. This setting is a security measure that protects your server from session bombing (i.e., preventing the server from starting more sessions than memory and CPU can handle).

  • Normally, this value should be set to the highest number of sessions your server can handle without running out of memory.
  • Alternatively, if you do not have a dedicated server, you might want to set this to a lower value, effectively saving memory and CPU resources for use by other applications and services on your server.

This setting can be used to queue or deny incoming requests. If the max is set to 100 (the default) and the system has 3 processes running, the 4th through 100th incoming requests are queued. If you set the value to 4, the 5th request will immediately receive an error 500. Therefore, especially with a small server (or a Lite Web Application Server), this value plays an important role in the user experience. This is combined with an HTTP timeout at the client. If that timeout fires before the queued request is handled, you will receive another error.
