Managing web proxy cache settings

You can configure the web proxy cache size for VCX-10 to VCX-90 SteelHeads in the Editing Appliance Configuration: <hostname>, Web Proxy Settings page.

You can configure the total cache size in the SCC Web Proxy Settings page for the managed VCX-10 to VCX-90 models.

If you make a change to the web proxy cache size and web proxy is running, the web proxy is automatically restarted.

Any changes to an already configured web proxy cache size will purge the cache. We recommend that you make changes to the web proxy cache size cautiously.

Disabling web proxy on VCX models will disable all web proxy alarms but it will not affect the existing cache.

This feature applies only to SteelHead VCX-10 to VCX-90 models.

For more about web proxy, see About Web Proxy. and the SteelHead User Guide.

To configure web proxy cache settings, choose Manage > Topology: Appliances. Select the VCX appliance you want to edit to display the Edit Appliance tab. Select the Appliance Pages tab to display the Appliance Configuration Pages list.

Under Appliance Configuration Pages, click Web Proxy Settings to display the Editing Appliance Configuration: <hostname>, Web Proxy Cache Settings page. These configuration options are available under Web Proxy Cache Settings:

Specifies the minimum web proxy cache size in gigabytes (GB), as specified by the license. The minimum cache size is 5 GB. This value is updated after a policy push or a change is detected in the license.

Specifies the maximum cache size in gigabytes (GB), as specified by the license. This value is updated after a policy push or a change is detected in the license. The maximum cache size is 800 GB, depending on the available disk size and your license maximum size. The maximum cache size can’t exceed the available disk space. If you exceed the available disk space, an alarm is triggered.

Specifies the disk space used by the current web proxy cache. This value is updated after a policy push or a change is detected in the license. The actual disk size differs if the cache size isn’t configured or if the disk doesn’t have enough disk space for the configured cache size.

Specifies the total cache size in gigabytes (GB). This value is your configured cache size. If the configured cache size is larger than what the management disk can support (that is, the actual cache size) then an alarm is raised.
