Use this topic to configure a cache rule that is associated to a URI group for the on demand router (ODR). HTTP 1.1 defines a set of rules for ODRs to cache content. Static cache rules enable these default rules to be overridden for a given address space. For the rules to have meaning, you must enable caching on the administrative console page.
To view this administrative console page, click .
To change the ODR settings, you must have administrator or configurator administrative privileges.
You can edit ODR setting fields on the Configuration tab.
URI groups, along with the virtual host, define the scope of the address space to have cache customization performed.
The name field cannot contain the following characters: # \ / , : ; " * ? < > | = + & % '
The name that is defined must be unique among URI groups and cannot begin with a period or a space. A space does not generate an error, but leading and trailing spaces are automatically deleted.
Disables caching for this address space. A user may wish to disable caching for a set of content servers that are known to contain sensitive or highly-personalized information.
The default is false, which indicates that caching is enabled for the URI group.
The default expiration value, in seconds, that is used to determine the validity of a cached response when all other HTTP 1.1 caching-related response headers do not give guidance. The default value is sufficient in most environments.
The percentage of a Last-Modified header for a response that determines the validity of a cached response when the response does not have explicit HTTP expiration headers. The default value is sufficient in most environments.
The default for this field is 0.0.
Name of the virtual host, along with the URI group, defines the address space to have cache customization performed.
