4.3.1 Configuring Caching Options

The Cache Options allow you to control how Access Gateway caches objects.

  1. Click Access Gateways > Edit > Cache Options.

  2. To disable caching of all web server content, select Disable Caching.

    When this option is selected, all other caching options are disabled.

  3. Modify the Cache Freshness settings. Use the Reset button to return these settings to their default values.

    These options govern when the proxy service revalidates requested cached objects against those on their respective origin web servers. If the objects have changed, the proxy service re-caches them.

    WARNING:Enter whole number values. Decimal values (2.5) are not supported and generate an XML validation error.

    HTTP Maximum: Specifies the maximum time the proxy service serves HTTP data from cache before revalidating it against content on the origin web server. No object is served from cache after this value expires without being revalidated.

    This overrides a freshness or Time to Expire directive specified by the Webmasters if they specified a longer time.

    You use this value to reduce the maximum time the proxy service waits before checking whether requested objects need to be refreshed. The default is 6 hours.

    HTTP Default: Specifies the maximum time the proxy service serves HTTP data for which Webmasters have not specified a freshness or Time to Expire directive. The default is 2 hours.

  4. To save your changes to browser cache, click OK.

  5. To apply the changes, click the Access Gateways link, then click Update > OK.
