Subject Re: Should "Cache Manager" cache content with Cache-control=private?
Date Sun, 08 Jul 2012 09:45:09 GMT
Reading specification:
private Indicates that all or part of the response message is intended for
a single user and MUST NOT be cached by a shared cache. This allows an
origin server to state that the specified parts of the
response are intended for only one user and are not a valid response for
requests by other users. A private (non-shared) cache MAY cache the

*Note:* This usage of the word private only controls where the response may
be cached, and cannot ensure the privacy of the message content.

So I agree with you "titou10 titou 10" that JMeter should cache entry. I
checked code and in fact it is not doing so.
Bug is now fixed:


Feel free to download nightly build when it's available and check if issue
is fixed for you
