Help | Content Gateway | Version 7.7.3

Throttling Net Connections

Specifies the maximum number of network connections that Content Gateway accepts.

Setting a Content Gateway throttle limit helps to prevent system overload when traffic bottlenecks develop. When network connections reach this limit, Content Gateway queues new connections until existing connections close.

Do not set this variable below the minimum value of 100.

Maximum Connections

Specifies the maximum number of client connections allowed before the ARM starts forwarding incoming requests directly to the origin server. The default value is 1 million connections.

If you change this option, you must restart Content Gateway.

Concurrent Connection Limit: Maximum concurrent connections

Specifies the maximum number of concurrent HTTP/HTTPS connections a client is allowed. The default is 1000. The supported range is: 1 - 45000

Concurrent Connection Limit: Alert when limit exceeded

When enabled, causes Content Gateway to generate an alert when a client exceeds the maximum concurrent connection limit.

In addition to displaying the alert in Content Gateway Manager, it is also logged in /var/log/messages and content_gateway.out.

Concurrent Connection Limit: Close excessive connections when limit exceeded

When enabled, causes Content Gateway to close excessive connections when the limit is exceeded.

Connection Rate Limit: Maximum connection rate

Specifies the maximum connections per second, averaged over a minute, that a client can make. The default is 100. The supported range is: 1 - 1000

Connection Rate Limit: Alert when limit exceeded

When enabled, causes Content Gateway to generate an alert when a client exceeds the maximum connection rate limit.

In addition to displaying the alert in Content Gateway Manager, it is also logged in /var/log/messages and content_gateway.out.

Connection Rate Limit: Close excessive connections when limit exceeded

When enabled, causes Content Gateway to close excessive connections when the limit is exceeded.

Specifies IP addresses and/or IP address ranges to which connection limits are not applied. IP addresses can be IPv4 or IPv6 (IPv6 support must be enabled). Multiple addresses or ranges can be specified in a comma-separated list.

Low Memory Mode

Specifies whether Content Gateway suspends scanning of Web traffic when the host system experiences a low-memory condition.

Note: In this state, URL filtering is applied as usual.

Low Memory Mode: Enabled/Disabled

Select Enabled to suspend scanning during a low memory condition.

Low Memory Mode Duration

Specifies the length of time, in minutes, that scanning is suspended.

If the low memory condition resolves itself before the timer expires, scanning resumes and the low memory mode trigger resets.

If the timer expires, scanning resumes and the low memory mode trigger is not reset.
