No special prerequisites.

The following procedures explain how to configure Apache server options using InterWorx. The most common configuration options are exposed in the InterWorx Cluster Panel interface. As with many of the system services, a system administrator still retains the ability to configure the service by editing the configuration file.

1. Click on the System Services menu if it is not already expanded.
2. Click on the ♦    Web Server item.
3. You should now be looking at the Webserver Management controls in the main content area.
4. Locate the Apache Server Options section.
5. Change the option(s) you wish to update to the desired value(s).
6. Click the Update button.
7. You will see the following set of messages at the top of the screen:

   » Service successfully restarted
   » Apache options updated successfully

Apache docs on Start Servers directive

The minimum number of idle child processes. An idle process is one which is not handling a request. Possible values range from 1 to 20000.

Apache docs on the Minimum Number of Spare Servers

• The total amount of time for a GET request to be received.
• The amount of time between receipt of TCP packets on a POST or PUT request.
• The amount of time between ACKs on transmissions of TCP packets in responses.

Apache docs on TimeOut directive

Turning the Keepalive directive on will provide long-lived HTTP sessions which allow multiple requests to be sent over the same TCP connection. In some instances, turning keepalive on has resulted in a reduction in latency for HTML documents containing many images.
