Amos, I want to find out what is filling my disk at 2-3MB/s. If there
is no cache related information in the response header, will squid
write the response to the disk?
In squid wiki, I found the following sentences:
Responses with Cache-Control: Private are NOT cachable.
Responses with Cache-Control: No-Cache are NOT cachable.
Responses with Cache-Control: No-Store are NOT cachable.
Responses for requests with an Authorization header are cachable ONLY
if the reponse includes Cache-Control: Public.
The following HTTP status codes are cachable:
200 OK
203 Non-Authoritative Information
300 Multiple Choices
301 Moved Permanently
410 Gone
My question is: If there is no Cache-control related information, such
as the following header
Server nginx/0.8.54
Date Thu, 18 Aug 2011 15:56:29 GMT
Content-Type application/json; charset=UTF-8
Content-Length 1218
X-Cache MISS from zw12squid.my.com
X-Cache-Lookup MISS from zw12squid.my.com:80
Via 1.0 zw12squid.my.com (squid/3.1.12)
Connection keep-alive
will squid save it to disk?
Can you give me a detailed description about when will squid save the
object to disk?
thanks a lot for your kind help.
