7 Modify the pages on the Web server that you want to the set custom caching intervals for the
Access Gateway. To the HTTP header, add a string similar to the following:
MYCACHE:600
The numeric value indicates the number of seconds the Access Gateway can retain the object in
cache. A value of zero prevents the Access Gateway from caching the object. This cache
interval can be different than the value set for browsers (see
How Custom Cache Control Headers Work," on page
8 Ensure that the Web server continues to send the following standard HTTP cache-control
headers:
Cache-Control: Max-Age headers that cause browsers to cache object for no longer than
two minutes.
Cache-Control: Private headers that cause external caches to not cache the objects.
When your Web server sends an object with the MYCACHE header in response to a request made
through the Access Gateway, the proxy service recognizes the custom header and caches the object
for 10 minutes. Requesting browsers cache the object for only two minutes, and external caches do
not cache the object.
Thus, the Access Gateway off-loads a processing burden from the Web server by caching the
frequently requested objects for 10 minutes (the value you specified in
other hand, must always access the Access Gateway to get the objects if their previous requests are
older than two minutes. And the objects in the cache of the Access Gateway are kept fresh because
of their relatively brief time-to-live value.

5.4 Configuring a Pin List

A pin list contains URL patterns for identifying objects on the Web. The Access Gateway uses the
list to prepopulate the cache, before any requests have come in for the content. This accelerates user
access to the content because it is retrieved from a local cache rather than from an exchange with the
Web server, which would read it from disk.
You can use the pin list to specify the following:
Which objects you want to cache
Which objects you never want cached
The pin list is global to the Access Gateway and affects all protected resources. The objects remain
in cache until their normal cache limits are reached or they are bumped out by more recently
requested objects.
To configure a pin list:
