Novell ACCESS MANAGER 3.1 SP2 - ACCESS GATEWAY GUIDE 2010 Manual page 171

Revalidate: Causes the proxy service to check whether the current information is valid. If
it is, the currently cached information is returned. If it isn't valid, the request is forwarded
to the Web server.
Ignore: Causes the proxy service to ignore the request and send the data from cache
without checking to see if the cached data is valid.
5 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.
HTTP Minimum: (Access Gateway Appliance) Specifies the minimum time the proxy service
serves HTTP data from cache before revalidating it against content on the origin Web server.
No requested object is revalidated sooner than specified by this value.
This overrides the freshness or Time to Expire directive specified by the Webmasters if they
specified a shorter time.
You can use this value to increase the minimum time the proxy service waits before checking
whether requested objects need to be refreshed. This parameter does not override No Cache or
Must Revalidate directives from the origin Web server.
The default value is 0, which allows the proxy service to honor the Time To Expire directive of
each object (unless it is longer than the HTTP Maximum option). If the HTTP Minimum option
is set to a value other than 0, the value overrides any object's Time to Expire directive that is
shorter than the value set. The default is 0.
Continue Fill Time: (Access Gateway Appliance) Specifies the how long the proxy service
ignores browser request cancellations and continues downloading objects from the target Web
server until the download is complete. The default is 1 second.
HTTP Retries: (Access Gateway Appliance) Specifies the number of retry requests to issue to
a Web server. The default is 4 retries.
