Re: [squid-users] cache of 404 and redirects

Chris, I tried the below and also added

The Cache Control header is now set to "public", but it still fails to retrieve the content from the cache. A bug?

/usr/local/squid/bin/squidclient -p 3128 -h 192.168.75.133 http://www.google.com/idontexist
HTTP/1.0 404 Not Found
Cache-Control: public

Not much you can do in this instance...

-bash-3.00$ squidclient -p 8080 http://www.google.com/idontexist
HTTP/1.0 404 Not Found
Cache-Control: private
Content-Type: text/html; charset=ISO-8859-1
Date: Tue, 06 May 2008 23:17:34 GMT
Server: gws
...

The Cache-Control: private " [i]ndicates that all or part of the
response message is intended for a single user and MUST NOT be cached by
a shared cache" according to RFC 2616.
