Detailed Description

This class stores Addresses off different Cache-Proxies.

It can be used for Load Balancing between them. Currently a simple Ropund Robin is implemented.

get()

CASocketAddrINet* CACacheLoadBalancing::get

(

)

Gets the 'next' Address according to the Load-Balancing algorithm.

This is the Address which should be used for a connection to a cache proxy.

Returns

next Address of a Cache-Proxy
