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
