You also need to ensure that the DNS server configuration information is set.

For HTTPS caching, you need to ensure that the certificate used for HTTPS caching is trusted by your clients.
Preparing & Trusting a Certificate for Encrypted Traffic
If you have an upstream proxy in your environment, you can configure it as a proxy peer to ensure that Edge Cache
can fetch content from the Internet.
You can add one or more Edge Cache policies to a virtual circuit in the Optimizer.
For more information, refer to
Creating an Edge Cache Policy in the Optimizer
. Then you can start the Edge Cache process.
Since the appliance has dynamic disk partitioning, if needed, you can increase the cache storage capacity dynam-
ically.
For more information, refer to
Once Edge Cache is configured and started, you can monitor the caching performance.
You can look at the Edge Cache monitor to determine the reduction ratio or throughput comparing the LAN (cached
and non-cached) data to the WAN (non-cached) data. The Edge Cache monitor will also report the requests per second
versus the hits per second, where hits are the number of requests that could be satisfied by cached content. These
charts can look at long term historical caching or can be as little as the last 5 minutes with 10 second samples.
Monitoring edge cache reduction
You can also look at the Real Time page to see which conversations are passing through Edge Cache. Conversations
with a blue background indicate that the flow passed through Edge Cache, however, it does not necessarily mean that
any of the requests were satisfied by cached content.

Edge Cache Configuration
When web objects are downloaded from the Internet or across WAN links, Edge Cache stores them at the edge of the
network. When subsequent requests come for the same material, the content is quickly delivered from the Edge Cache
without the need to download the data again over the WAN. Edge Cache can cache web objects, videos, software
updates, and other content on the WAN. You can control whether to exclude particular sources, or sizes of objects from
being cached. The cache objects can also be shared among peer appliances if desired, meaning that if the content
cannot be found in the cache of the appliance through which the traffic is passing, then the appliance can request the
content from peer appliances. You are also able to clear the cache, if desired.
To learn the details of how edge cache works, see
or to learn all the details of how to configure
Edge Cache including configuring DNS and HTTPS certificates and blacklists and whitelists, see the

You may want to limit the size of objects that can be cached. Since the cache storage size is limited, you may want to
decide whether to allow a few large objects or lots of little objects. You should ensure that the size is aligned with the
types of objects that you want to be cached. For example, iOS updates tend to be approximately 1 GB and Mac updates
tend to be 6 GB and so if you want Edge Cache to help with caching of these updates, you'll want to ensure that the
minimum and maximum allowed objects size accommodates these sizes.
You may want to blacklist particular sites if Edge Cache is not working properly and is preventing the network user from
getting access to the site. Also, you may want to blacklist secure sites because you do not want to cache sensitive data
such as financial or banking sites. Alternatively, if you want to only cache particular secure sites once they've been
identified as important to your network, you can whitelist them such that only those sites listed will be cached.
Whitelisting is only available for HTTPS caching. You can specify your whitelist and blacklist as source IP, destination IP,
source domain, or destination domain. Domains are resolved using the DNS.
