Hey All,
Does squid cache web-pages when configured in the forward interception
proxy mode i.e http_port x:y intercept.? If so how can it be turned
off.?
"cache deny all" does what you ask.
I actually want to bench-mark squid performance in terms of
requests-per-second that squid can support.
Disabling caching will not tell you that. It will tell you the average speed
of Squid under DoS or worst-case traffic conditions. ie the minimum
capacity.
In a way, i am actually interested in the capacity of squid. I do not
want to include the cache functionality of the proxy. Not including
the cache will mean what numbers squid can support when all requests
are distinct, when the request/response are all new i.e no CACHE_HIT.
So every time squid has to go to the origin and pull the full body
data.
Servicing data of the cache is a big advantage of squid. But we need
to see the performance of squid without cache if we need to see the
data-path latency(or lower requests/sec) introduced by squid. Cache
add a negative time factor to improve the latency.

Your testing will likely show otherwise. Compare the speed of a config
of "cache deny all" with a config having no cache lines ("cache" or
"cache_dir") but some space for mem_cache. Most people find that much
faster than not caching.
