Yes that's right. The load balancer we are using has a global cache policy.
It means that some of the clients are destination web servers in some cases.
When  I use a local policy the routing loop does not occur.

Hi,

When you have ipspoofing enable in Netcache, it will open, a new sessions
with the server witch have the content with the client IP.  For some reason,
I don?t know detais of your installation,  the name resolution method(DNS,
host file, etc...) are telling to the Netcache that the destination
IP(server farm) is the client IP 212.179.201.148.  Well SIP = DIP is a
looping.

Assunto: [load balancing] Routing loop on Netcache


Hi all,

Does anyone know why Netcache would cause following log message? We are load
balancing Netcache with Foundry SI400. Spoofing and cache-router-offload is
enabled:

Sun May 19 15:39:07 IDT [sthread_loop:warning]: Potential routing loop
detected for Url ("/") in HTTP X-Forwarded-For header: 212.179.201.148,
212.179.201.148,
Sun May 19 15:41:20 IDT [sthread_loop:warning]: Potential routing loop
detected in HTTP Via header: 1.1 proxy-ptk-primary (NetCache

Any thoughts?
