Transparent proxy caching with WCR
Browser sends requests for web pages to origin server
LAN switch (Cache Redirector) in data path examines all packets and redirects web traffic to cache(s)
Very little impact on non-web traffic
No browser re-configuration required
Cache need not do NAT, the redirector can offload this function from the cache.
Each client hits multiple caches
- Takes advantage of data stored in all local caches, raising hit rate
- Higher hit rates mean less user delay and less unnecessary WAN traffic
- If any cache is down, traffic directed to other caches
