Hello,
I'm attempting to get the web-polygraph software working with Squid
and am having trouble in that squid doesn't seem to think any of the
content served up by polysrv is cacheable. The specifics are:
OS => FreeBSD 4.4
Squid => squid-2.4-200201240000
Web Polygraph => polygraph-2.7.5
Squid configuration is the stock squid.conf with "http_access deny all"
replaced by "http_access allow all".
Web Polygraph is the stock simple.pg with the server and robot address
changes described in section "4. Adding a proxy" of the "Getting Started"
document.
After much prowling around I believe the following is the smoking gun
from the squid cache.log (with debugging turned on):
2002/01/24 11:45:32| refreshCheck: 'http://10.10.20.11:9090/w05ef1a0e.3c8d1bf6:0

2002/01/24 11:45:32| STALE: age 60 > min 0

that was generated in response to the following HTTP reply:

A minor problem with this is I don't know where it gets the "age" value
from to determine that the reply is stale (which is how I interpret the
first log extract).
A major problem is I don't know how to change the behavior of the
polysrv/squid combo to do the right thing.
Any help would be greatly appreciated!
