5.4.2 Pin Type

The pin type specifies how the Access Gateway caches objects that match the URL mask.
Normal: The Access Gateway handles objects matching the mask in the same way it handles
any other requested objects. In other words, the objects are cached but not pinned.
Administrators often use this pin type in combination with a broad URL mask that has a bypass
pin type. This allows them to insulate specific objects from the effects of the bypass rule.
For example, you could specify a URL mask of
URL mask of
including
requested. Assuming there are no other URL masks in the pin list, all other JPG graphics are
not cached because of the
Bypass: The Access Gateway does not cache the objects. In other words, you can use this
option to prevent objects from being cached.

5.5 Configuring a Purge List

The purge list is global to the Access Gateway and affects all protected resources. This option allows
you to specify URL patterns or masks for the pages and sites whose objects you want to purge from
cache.
When defining the masks, keep in mind that the Access Gateway interprets everything in the URL
mask between the asterisk wildcard (*) and the following delimiter as a wildcard. Delimiters include
the forward slash (/), the period (.), and the colon (:) characters. For example:
URL Mask
/*.pdf
www.foo.gov/contracts/*
This option also allows you to purge cached objects whose URL contains a specified query string or
cookie. This mask is defined by placing a question mark (?) at the start of the mask followed by text
strings and wildcards as necessary. String comparisons are not case sensitive. For example,
?*=SPORTS purges all objects with the text "=SPORTS" or any other combination of uppercase and
lowercase letters for "=SPORTS" following the question mark in the URL.
IMPORTANT: If you also configure a pin list, carefully select the objects that you add to the pin
and purge lists. You can configure the Access Gateway to use the pin list to add objects to the cache
and to use the purge list to remove the same objects.
