RE: [squid-users] Re: Problems checking if an object is in cache or not

You are right.

The TRACE method was disabled in the Server (Tomcat). I enabled it in squid.conf and in server (tomcat).
Now TRACE method works, but X-Cache and X-Cache-Lookup options values are "MISS" in both cases.
In access.log file I can see that when the resource is asked a TCP_HIT trace appears, and not a TCP_MISS trace. I capture traffic with wireshark and client doesn't ask the file.

I saw in internet that I should use squidclient with -t option to check if an object is cached.
Why need I enable TRACE on server to check if a object is cached in the client (Squid)?
I need to ask to squid directly if an object is cached or not without server intervention. How can I do it?

Presumably you aren't allowed to use the TRACE method, try it without
the -t option.

It's the error message that's a MISS not the object.
