Hi, 

we want to configure a transparent proxy with 

a) trend micro iwss (commercial virusprotection, no-caching proxy)
b) squid (caching-proxy, SquidGuard)

Problem: 

Squid configured as parent for trend does not cache any requests. 
Trend configured as parent for squid does not cache any requests as well. 

As a single proxy squid works great. We tried a solution with iptables 
redirecting port 80 (squid)  to port 8080 (trend). 
It works, but there must be a more beautiful solution. 

Does someone know how to teach squid using a  parent (i.e. trend), making no 
direct connections and  caching data ??

We made him using trend as single parent without any direct requests. But we 
can't teach him to cache data as well. 

Single proxy -> very well hit rate 
with trend as parent -> 100% TCP_MISS


Thanks, 

Ralf Frochte
