vqServer Servers and ports


Each instance of vqServer consists of two or more servers, each of which listens for HTTP requests for web pages on a different TCP/IP port. Each server can be administered and configured independently of the other server(s).

The default vqServer installation consists of two servers: the main web server, which listens on port 80, and the administration server, which listens on port 9090.

You can switch servers on and off and change the administration server port from the vqServer console. Other options are controlled from the servers page of the vqServer control centre.

Servers page

This page is displayed when you click on Servers in the control centre menu.

The main part of the page lists each server managed by the control centre, ordered by TCP/IP port number. You can

  • Start or stop a server by clicking on the icon in the Start/stop column. You can't stop the administration server from the control centre.
  • Delete a server by clicking on the icon in the Delete column. You can't delete the main web server or the administration server.

The control centre menu for this page includes:

  • a link for each server; click on this link to see the options for this server.
  • the New server link which adds a new server to the list and opens the new server's settings page.

Server settings page

This page is displayed when you click on Settings in a server options submenu in the control centre menu.

This page provides control over the server's main settings.

Port

The TCP/IP port on which the server listens for HTTP requests for web pages. This can be any number between 1 and 32768. The default is 80 for a Windows system and 8080 for UNIX-based systems for World Wide Web requests. Any other port number has to be specified in the request.

If you change this setting, vqServer automatically stops the server, changes the port and starts it again with new default log file names (the existing log files are not renamed).

Description

The name used by vqServer to identify the server to the system administrator. This can be anything you like.

Minimum threads

This is the number of HTTP connection handler threads which the server tries to keep available to process incoming requests. vqServer uses thread caching to minimise the overhead associated with creating, initialising and destroying HTTP connection handler threads unnecessarily. Setting this to -1 disables thread caching. Suggested value: 10.

Maximum threads

This is the maximum number of HTTP connections which the server will try to deal with at the same time. Attempted connections in excess of this number are queued by your computer's TCP/IP stack. Suggested value: 100.

On

This check box provides another method of switching the server on and off.
