Setting browser auto configuration options

The Autoconfiguration of Browsers section lets you specify an auto configuration file for the selected node. Web browsers use the appliance by specifying a preference to use a proxy server, usually through an auto configuration file.

Note Users must set their browsers to connect to the appliance’s auto configuration file. For information on setting your browser to use a proxy, such as the appliance, see your browser documentation. If you are using the transparency option, you do not need auto configuration files.

The following table describes the section’s options.

Setting throttling of network connections

The Throttling of Network Connections section lets you set a limit on the number of connections the appliance can have. Setting limits on the connections helps to prevent system overload when traffic bottlenecks develop. When network connections reach the limit, new connections are queued until existing connections close.

Note This section is available only if transparency is disabled. If you enable transparency, you do not see this option. See Configuring load-shedding‚ on page 28 for information about the transparency load shedding option.

The following table describes the section’s options.

Configuring load-shedding

The Load Shedding section lets you configure how the appliance handles overloaded conditions.

When transparency is enabled, the appliance handles overload conditions by forwarding a percentage of new requests to origin servers. You can configure the appliance to automatically shed load if the HTTP-hit transaction times become too long. For example, suppose that the lower limit for HTTP hit-transaction time is 500 milliseconds and the upper limit is 1000 milliseconds. Given these limits, the following is true:

If it takes the appliance more than 500 milliseconds to serve a fresh hit, it begins to shed load.
