Configuring Web Caching
The following are the steps in configuring web caching on the IA:
1.
Create the cache group (a list of cache servers) to cache Web objects.
2.
Specify the hosts whose HTTP requests will be redirected to the cache servers. This
step is optional; if you do not explicitly define these hosts, then all HTTP requests are
redirected.
3.
Apply the caching policy to an outbound interface to redirect HTTP traffic on that
interface to the cache servers.
Creating the Cache Group
You can specify either a range of contiguous IP addresses or a list of up to four IP
addresses to define the servers when the cache group is created. If you specify multiple
servers, load balancing is based on the destination address of the request. If any cache
server fails, traffic is redirected to the other active servers.
To create the cache group, enter the following command in Configure mode:
Create the cache group.
Note:
If a range of IP addresses is specified, the range must be contiguous, with a
maximum of 256 addresses
Specifying the Client(s) for the Cache Group (Optional)
You can explicitly specify the hosts whose HTTP requests are or are not redirected to the
cache servers. If you do not explicitly specify these hosts, then all HTTP requests are
redirected to the cache servers.
To specify the clients or non-clients for the cache group, enter the following commands in
Configure mode:
Define hosts whose requests are
redirected to cache servers.
Define hosts whose requests are
not redirected to cache servers.
