222 Chapter 7 Web cache configuration
Setting the action the cache performs when a Web server
error occurs
Originating Web servers sometimes send errors to users. Typically, this happens
when a user requests Web content from an originating Web server that is down or
is not responding. In this situation, you can select one of two responses the Instant
Internet unit makes:
• Send the Web entry it has stored in the cache if the Instant Internet unit fails to
connect to the originating Web server, even if the cache entry is expired.
• Return the connection failure error message to the user.
To set the action the cache performs in response to an originating Web server
error:
1
On the Home page, click Web Cache.
The Web Cache page opens.
2
On the Web Cache page, click Configure.
The unit Configuration page opens.
3
In the Web Cache Level area, click Customize.
The Custom Cache Level page opens.
4 In the Request/Response Options area, select or clear the Return expired
cache entry on server error check box.
Click Help for more information about each field on any page.

Resetting cache statistics

When you change configuration options, you may want to reset the statistics to
measure how the new configuration affects cache usage. Resetting statistics does
not delete cached entries; it clears past results so that the statistics reflect cache
usage with the current settings. To delete all entries in the cache, restart the Instant
Internet unit. For details, refer to
