Dear all, If we conceder the following deployment diagram: INTERNET | +--------------+ |Load Balancer | +--------------+ | | +-------+ +-------+ |Squid_1| |Squid_2| +-------+ +-------+ | | +--------+ +--------+ |Apache_1| |Apache_2| +--------+ +--------+ There the squid servers are configured as reverse proxies in front of the apache backend (original/parent) servers. The apache servers are identical. That means that the same HTTP/Get request performed on either of them will always produce the same response. As a result the all responses will be cached twice. Once on squid_1 and again on squid_2. Is it possible to avoid the redundancy explained above with the help of the ICP protocol and configuring both squid servers as sibling peers? Any ideas will be appreciated! Best regards, Christian This e-mail message contains information which is confidential and may be privileged. It is intended for use by the addressee only.
